Plugin update and backup

Also as last time could you plz also take backup of live database ,
We will take backup of files
Correct above sentence

Also, as before, could you please take a backup of the live database? We will handle the backup of the files.

### 1. **Check WordPress and Site URL Settings**
– Go to **Settings > General** in your WordPress dashboard.
– Ensure both the **WordPress Address (URL)** and **Site Address (URL)** start with `https://`.

### 2. **Update .htaccess File (If Necessary)**
– If the server is not forcing HTTPS, update your `.htaccess` file to redirect all HTTP traffic to HTTPS.
– Add the following rules (if you're using Apache):

<IfModule mod_rewrite.c>
     RewriteEngine On
     RewriteCond %{HTTPS} !=on
     RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
     </IfModule>

### 3. **Check WooCommerce Email Settings**
– Verify the email content and links generated by WooCommerce.
– Links are typically generated using `wc_get_endpoint_url()`, which uses the site URL settings. If these settings are correct, the links should automatically use HTTPS.

### 4. **Update or Force HTTPS in wp-config.php**
Add this to `wp-config.php` to force HTTPS:

define('FORCE_SSL_ADMIN', true);
   if (strpos($_SERVER['HTTP_X_FORWARDED_PROTO'], 'https') !== false) {
       $_SERVER['HTTPS'] = 'on';
   }

### 5. **Use a Plugin to Ensure HTTPS**
If you're still having issues, install a plugin like **Really Simple SSL** to force HTTPS across your site, including the reset password links.

### 6. **Clear Cache**
– Clear all caches, including your WordPress cache and any server or CDN caches (e.g., Cloudflare), to ensure changes take effect.

### 7. **Test Again**
– Go to the **Forgot Password** form, request a reset link, and verify the email. The URL should now use HTTPS.

Let me know if you encounter any specific errors!

### Example Hook to Force HTTPS in Reset Password Link

Add the following to your theme's `functions.php` file or a custom plugin:

add_filter('retrieve_password_message', function ($message, $key, $user_login, $user_data) {
    // Extract the reset password link from the message.
    $site_url = site_url('wp-login.php?action=rp&key=' . $key . '&login=' . rawurlencode($user_login));
    
    // Ensure the link uses HTTPS.
    $site_url = set_url_scheme($site_url, 'https');

    // Replace the reset password link in the email message.
    $message = str_replace(wp_login_url(), $site_url, $message);

    return $message;
}, 10, 4);

### How This Works:
1. **Filter**: The `retrieve_password_message` filter intercepts the email content generated for the reset password email.
2. **Force HTTPS**: The `set_url_scheme()` function is used to ensure the link is HTTPS.
3. **Replace**: It updates the link in the email content before sending it.

### Debugging:
After adding this, trigger a password reset and:
– Verify the email content to ensure the link is updated to HTTPS.
– Clear any email-related caches to avoid old content being served.

Let me know if this resolves your issue or if further adjustments are needed!

### Steps to Fix the Issue

#### 1. **Check Your Email Service Settings**
– If you're using an email delivery service (e.g., Mailgun, SendGrid, or a custom SMTP provider), log in to the service's dashboard.
– Look for settings related to **click tracking** or **link wrapping**. Disable these options if possible.
– Ensure the service is not modifying links unnecessarily.

#### 2. **Verify Your WordPress Email Configuration**
– Confirm how your WordPress emails are being sent. If you're using an SMTP plugin like **WP Mail SMTP**, check its configuration.
– Test whether the issue persists when sending emails directly via the default PHP mailer.

#### 3. **Override the Reset Password Link**
You can intercept and fix the reset password link before it's sent, overriding any external modifications. Add this code to your theme's `functions.php` or a custom plugin:

add_filter('retrieve_password_message', function ($message, $key, $user_login) {
       // Generate the correct password reset URL.
       $reset_url = network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login));
       $reset_url = set_url_scheme($reset_url, 'https');

       // Replace the reset password link in the email message.
       $message = preg_replace(
           '/https?://[^s]+/', // Matches any URL.
           esc_url($reset_url),
           $message
       );

       return $message;
   }, 10, 3);

#### 4. **Force HTTPS on External Service**
If disabling link tracking isn’t an option, ensure the external service correctly handles HTTPS links. Contact their support team and ask if:
– HTTPS can be enforced for all wrapped links.
– Their system respects `https` links in the original email.

#### 5. **Test Again**
– Trigger a password reset request and inspect the email. Confirm that the reset link is using HTTPS and is not being incorrectly modified.

If you're still experiencing issues, please share more details about your email setup or any third-party tools in use for email delivery.

—

### 1. **Check Your Email Delivery Service**
– **Identify the Service**: Determine if your emails are being routed through a third-party service like:
– Mailgun
– Postmark
– SendGrid
– Amazon SES
– A specific hosting provider's email relay

– **Disable Link Tracking**: Log in to the email service's dashboard and look for settings related to **link tracking** or **click tracking**. Turn this off, as it is rewriting your links.

—

### 2. **Use HTTPS in WordPress and WooCommerce**
Ensure WordPress and WooCommerce generate the correct HTTPS links:
– Go to **Settings > General** in WordPress.
– Verify that both **WordPress Address (URL)** and **Site Address (URL)** start with `https://`.

—

### 3. **Force Correct Reset Password Link**
If the service is still altering the link, you can ensure WordPress sends the correct URL by adding a filter. Add the following code to your theme’s `functions.php` file or a custom plugin:

add_filter('retrieve_password_message', function ($message, $key, $user_login, $user_data) {
       // Construct the correct reset password URL.
       $reset_url = network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login));
       $reset_url = set_url_scheme($reset_url, 'https');

       // Replace all URLs in the message with the correct reset URL.
       $message = preg_replace('/http[s]?://[^s]+/', $reset_url, $message);

       return $message;
   }, 10, 4);

**Explanation**:
– This code overrides the reset password email content.
– It generates the correct password reset link and ensures it uses HTTPS.
– It replaces any URLs in the message with the correct reset URL.

—

### 4. **Test Email Sending**
Test the password reset email by:
– Triggering a password reset request from WooCommerce.
– Checking the email content to confirm that the correct HTTPS link is included and not altered.

—

### 5. **Use SMTP or a Different Email Service**
If the issue persists with your current setup:
– Install a plugin like **WP Mail SMTP** and configure it with a service like Gmail, SendGrid, or Amazon SES.
– Ensure the SMTP plugin or service does not modify the reset password links.

—

### 6. **Contact the Email Provider**
If disabling link tracking is not possible, contact the provider's support team. Ask them to:
– Whitelist your WooCommerce emails.
– Exclude specific types of emails (e.g., password reset emails) from link tracking.

—

### 7. **Fallback Solution: Custom Email Content**
If nothing else works, consider creating a custom password reset email template in WooCommerce or WordPress that includes the plain reset link, ensuring it is not rewritten.

Let me know if you need further assistance or detailed steps for any of these solutions!

### 1. **Disable Link Tracking in SendGrid**

To stop SendGrid from rewriting your URLs, follow these steps:

1. **Log in to your SendGrid Account**.
2. Go to **Settings > Tracking** in the SendGrid dashboard.
3. Find the **Click Tracking** section.
4. **Disable** the **Click Tracking** feature.

Disabling this should prevent SendGrid from rewriting the password reset link with their own tracking URL.

—

### 2. **Ensure Correct URLs in WordPress and WooCommerce**
Double-check that your **WordPress and WooCommerce** are configured correctly with HTTPS:

– Go to **Settings > General** in your WordPress dashboard.
– Make sure both the **WordPress Address (URL)** and **Site Address (URL)** use `https://`.

—

### 3. **Override the Password Reset URL in WooCommerce**

If disabling link tracking in SendGrid is not enough, you can force the correct HTTPS password reset link to be used by WooCommerce in your email by adding the following code to your theme’s `functions.php` file or a custom plugin:

add_filter('retrieve_password_message', function ($message, $key, $user_login) {
    // Generate the correct reset password URL.
    $reset_url = network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login));
    $reset_url = set_url_scheme($reset_url, 'https');

    // Replace any existing URL in the message with the correct reset URL.
    $message = preg_replace('/http[s]?://[^s]+/', $reset_url, $message);

    return $message;
}, 10, 3);

**Explanation:**
– The `retrieve_password_message` filter allows us to modify the email content before it is sent.
– We generate the correct reset password URL using `network_site_url()` and ensure it uses `https`.
– We use `preg_replace()` to replace any links in the message with the correct reset URL.

—

### 4. **Test the Changes**

After applying these steps, test the password reset process:

1. Request a password reset email through WooCommerce.
2. Check the reset password email and confirm that the link uses `https://` and is not being altered by SendGrid.

—

### 5. **Consider Using a Different Email Service (If Necessary)**

If you're still experiencing issues, and if disabling tracking in SendGrid isn't viable for your use case, consider switching to a different SMTP service or plugin like **Mailgun** or **Amazon SES**, which might offer more granular control over how links are handled.

—

Let me know how it goes or if you need further assistance with the SendGrid configuration!

### 1. **Disable Click Tracking in SendGrid**
– **Log into SendGrid** and go to **Settings** > **Tracking**.
– Disable **Click Tracking** to prevent SendGrid from rewriting the links.

This should stop SendGrid from replacing the reset password link with its own tracking link.

—

### 2. **Force Correct Reset Password Link Using a Filter**
Even though your URLs are correctly set to HTTPS, SendGrid's modification of links may still persist. To avoid this, you can force the correct URL in the WooCommerce password reset email.

Add the following code to your theme’s `functions.php` or a custom plugin to **override the reset password link**:

add_filter('retrieve_password_message', function ($message, $key, $user_login) {
    // Generate the correct reset password URL.
    $reset_url = network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login));
    $reset_url = set_url_scheme($reset_url, 'https'); // Ensure the URL uses HTTPS.

    // Replace any existing URLs in the message with the correct reset URL.
    $message = preg_replace('/http[s]?://[^s]+/', $reset_url, $message);

    return $message;
}, 10, 3);

This code works by:

– Generating the correct reset password URL using `network_site_url()`.
– Ensuring the link uses `https://`.
– Replacing any URLs in the reset email content with the correct password reset URL.

—

### 3. **Check for Other Possible Email Modifiers**
Sometimes, other plugins or security settings can modify emails or URLs. Here are a few things to check:

– **Caching plugins**: Ensure no caching plugin (like **W3 Total Cache**, **WP Super Cache**, or **LiteSpeed Cache**) is caching the password reset emails. Clear the cache if necessary.
– **Other Email Services**: Ensure that no other service (e.g., a custom SMTP plugin) is interfering with the email content.

—

### 4. **Test the Password Reset Process**
Once you've disabled Click Tracking and added the above filter, **test the password reset process**:
– Trigger a password reset on the site.
– Check the reset email to confirm that the link now uses `https://` and is not modified by SendGrid.

—

Let me know if this resolves the issue, or if you need further assistance!

Unfortunately, SendGrid has a **click tracking** feature that rewrites URLs in emails, which might be causing the issue. However, here’s how you can handle this:

### 1. **Disable Click Tracking in SendGrid**

The first step is to disable **Click Tracking** in SendGrid. This prevents SendGrid from modifying any links in the email content.

1. **Log into your SendGrid account.**
2. Navigate to **Settings > Tracking** in the SendGrid dashboard.
3. Find the **Click Tracking** section.
4. **Turn off** the **Click Tracking** feature.

This should prevent SendGrid from rewriting URLs with its own tracking link, and your password reset links will stay intact with `https://`.

—

### 2. **Use a Hook to Force HTTPS for Reset Password Links**

If disabling Click Tracking alone doesn't resolve the issue, you can use a custom filter to **force HTTPS** in the reset password link before the email is sent by WooCommerce. Add the following code to your theme’s `functions.php` or a custom plugin to override the reset password link:

add_filter('retrieve_password_message', function ($message, $key, $user_login, $user_data) {
    // Generate the correct reset password URL.
    $reset_url = network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login));
    
    // Ensure the reset URL uses HTTPS.
    $reset_url = set_url_scheme($reset_url, 'https');

    // Replace the reset link in the email message with the correct HTTPS link.
    $message = str_replace(wp_login_url(), $reset_url, $message);

    return $message;
}, 10, 4);

**Explanation:**
– This code uses the `retrieve_password_message` filter to intercept the password reset message before it is sent.
– It generates the correct reset password URL using `network_site_url()` and ensures that the URL uses `https://` using `set_url_scheme()`.
– It then replaces the URL in the message with the HTTPS version of the link.

—

### 3. **Test the Email**

Once you’ve made these changes:
1. Trigger a password reset request from WooCommerce.
2. Check the email and ensure the reset password link is correctly using HTTPS and is not being altered by SendGrid.

—

### 4. **Additional Configuration for SendGrid (if required)**

If you are still experiencing issues, you can also try these SendGrid settings:
– **Ensure the correct domain is authenticated** with SendGrid (using DKIM and SPF records).
– **Set the custom From email address** in SendGrid to match your site's domain. This may help ensure the correct link generation.

—

If you need further help, let me know!

Here’s how you can implement this:

### Step 1: Use WordPress Hook to Modify Reset Password Link

Add the following code to your theme's `functions.php` file or a custom plugin:

add_filter('retrieve_password_message', function ($message, $key, $user_login, $user_data) {
    // Generate the correct reset password URL.
    $reset_url = network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login));
    
    // Force the reset URL to use HTTPS.
    $reset_url = set_url_scheme($reset_url, 'https');

    // Replace the URL in the email message with the correct HTTPS reset link.
    $message = str_replace(wp_login_url(), $reset_url, $message);

    return $message;
}, 10, 4);

### Explanation:
– **`retrieve_password_message` Filter**: This WordPress filter allows you to modify the content of the password reset email before it's sent.
– **`network_site_url()`**: This function generates the password reset URL. The `network_site_url()` function automatically uses the site’s configured URL (which should be `https://` if your WordPress settings are correct).
– **`set_url_scheme()`**: This ensures that the generated URL uses `https://`, even if the base URL is `http://`.
– **`str_replace()`**: This replaces the old URL in the email message with the new, correct HTTPS reset URL.

—

### Step 2: Disable Click Tracking in SendGrid (if not already done)

To prevent SendGrid from rewriting the password reset URL, make sure **Click Tracking** is disabled:

1. Log into your **SendGrid** account.
2. Navigate to **Settings** > **Tracking**.
3. Turn off **Click Tracking**.

This will stop SendGrid from rewriting the reset password link.

—

### Step 3: Test the Changes

1. **Request a password reset** via WooCommerce.
2. **Check the email**: Verify that the reset link uses `https://` and is not modified by SendGrid.

—

By using this WordPress hook, you ensure that the reset password URL generated by WooCommerce will always use HTTPS, even if SendGrid or other email services modify the URL. Let me know if you run into any issues or need further clarification!

// Force the reset URL to use HTTPS.
$reset_url = set_url_scheme($reset_url, 'https');

// Replace the URL in the email message with the correct HTTPS reset link.
$message = str_replace(wp_login_url(), $reset_url, $message);

return $message;
}, 10, 4);
is not override

We will modify the password reset email and force the reset URL to use HTTPS by directly manipulating the `$message` and ensuring that we replace the password reset link with the correct HTTPS URL.

### Updated Code to Force HTTPS in Password Reset Links

Add this code to your theme’s `functions.php` or a custom plugin:

add_filter('retrieve_password_message', function ($message, $key, $user_login, $user_data) {
    // Generate the correct reset password URL using https.
    $reset_url = network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login));
    
    // Ensure the URL uses HTTPS.
    $reset_url = set_url_scheme($reset_url, 'https');

    // Replace the reset password link in the email with the correct HTTPS URL.
    // Look for the pattern of the URL and replace it with the correct URL
    $message = preg_replace('/http[s]?://[^s]+/', $reset_url, $message);

    return $message;
}, 10, 4);

### Explanation:

– **`preg_replace('/http[s]?://[^s]+/', $reset_url, $message);`**: This regular expression ensures that any URL in the message (specifically the reset password URL) will be replaced by the correct one that uses HTTPS. This should catch the SendGrid-modified link and replace it with your custom HTTPS link.
– **`set_url_scheme()`**: This forces the reset URL to use `https://`, even if the base URL is set to `http://`.

### Testing:

1. **Request a password reset** from your site.
2. Check the email to verify that the reset password link now uses `https://` and has not been altered by SendGrid.

—

### Alternative Approach

If this still doesn't work, consider trying a different approach by **disabling SendGrid’s link tracking entirely**, which can be done from the **SendGrid dashboard** under **Settings > Tracking** as mentioned earlier. This will prevent SendGrid from modifying any URLs, including the password reset link.

Let me know if this approach works for you or if you encounter any further issues!

The solution will involve **modifying the email content in WordPress** while keeping SendGrid's link tracking intact.

Here's an updated approach:

### Updated Approach to Force `https://` for Password Reset Link (Without Disabling SendGrid Tracking)

The key is to ensure that WordPress sends the correct password reset URL using `https://`, before SendGrid applies any link tracking.

We will **ensure the URL is correct in WordPress** and then allow SendGrid's tracking to happen on the correctly formed HTTPS link.

### Code to Force HTTPS for the Password Reset Link

Add this to your theme’s `functions.php` or a custom plugin:

add_filter('retrieve_password_message', function ($message, $key, $user_login, $user_data) {
    // Generate the correct reset password URL using https.
    $reset_url = network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login));
    
    // Force the reset URL to use HTTPS.
    $reset_url = set_url_scheme($reset_url, 'https');

    // Replace the password reset URL in the email message.
    $message = str_replace('http://', 'https://', $message);

    // Return the modified message.
    return $message;
}, 10, 4);

### Explanation:

– **`set_url_scheme($reset_url, 'https')`**: This ensures the password reset URL is explicitly set to use `https://`, no matter the base URL configuration.
– **`$message = str_replace('http://', 'https://', $message);`**: This will replace any occurrences of `http://` in the message with `https://`. It works even if SendGrid modifies the URL before sending the email.

### Testing the Solution:

1. **Request a password reset** from your WordPress site.
2. **Check the email**: Verify that the reset link is using `https://` and that SendGrid's click tracking does not modify it (this should still be intact as it modifies the URL after WordPress sends the email).

—

### Why This Works:

By modifying the email **before it’s sent** via the `retrieve_password_message` filter, you are ensuring that the link generated by WordPress always uses `https://`. Once SendGrid receives the email, it will track the correct `https://` link instead of altering it to `http://`.

Let me know how it works, or if you need further help!

Here are the methods for each:

### 1. **Using Apache (with `.htaccess`)**

If you're using Apache, you can force HTTPS by adding the following to your site's `.htaccess` file (located in the root of your WordPress installation):

# BEGIN HTTPS Redirect
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
# END HTTPS Redirect

### Explanation:
– **RewriteEngine On**: Enables mod_rewrite to process rules.
– **RewriteCond %{HTTPS} off**: Checks if the current connection is not secure (`https`).
– **RewriteRule**: Redirects the traffic to HTTPS. `%{HTTP_HOST}` is the domain, and `%{REQUEST_URI}` is the full path of the URL (e.g., `/page-name`).

This ensures that if anyone tries to access your site using `http://`, they will be automatically redirected to `https://`.

### 2. **Using Nginx Configuration**

If you're using **Nginx** as your web server, you can implement the redirection by adding the following to your Nginx server block (usually in `/etc/nginx/sites-available/default` or similar):

server {
    listen 80;
    server_name postmymeds.co.uk www.postmymeds.co.uk;

    return 301 https://$server_name$request_uri;
}

### Explanation:
– This `server` block listens for all HTTP requests (port 80).
– It then sends a `301 Permanent Redirect` to the same URL but with `https://`.

### 3. **Using WordPress Plugin (for Ease)**

If you're not familiar with server configuration or don't have access to the server configuration files, you can use a **WordPress plugin** to enforce HTTPS.

– **Really Simple SSL**: This plugin automatically detects your settings and configures your site to run entirely over HTTPS. It also handles the redirection for you.

– Install and activate the **Really Simple SSL** plugin.
– The plugin will automatically handle the redirect and ensure your site runs on HTTPS.

### 4. **Additional Considerations:**

– **SSL Certificate**: Make sure your server has a valid SSL certificate for **postmymeds.co.uk** and is correctly configured. Without it, the redirection won’t work properly.
– **Update Mixed Content**: After forcing HTTPS, check for mixed content (e.g., images or scripts loaded via HTTP). You can use plugins like **Better Search Replace** to replace all `http://` URLs with `https://` in your database.

—

### Summary:

– **Forcing HTTPS at the server level** using `.htaccess` (Apache) or an Nginx configuration will ensure that all traffic to your site uses HTTPS.
– If you're not familiar with server configurations, **Really Simple SSL** plugin is an easy way to enforce HTTPS in WordPress.

This approach ensures that **postmymeds.co.uk** always opens with HTTPS, including for the reset password links generated by SendGrid. Let me know if you need help with any of these steps!

Here’s how to fix this issue:

### 1. **Ensure WordPress Address and Site Address are Correct**
Make sure both **WordPress Address (URL)** and **Site Address (URL)** are set to use `https://` in the WordPress dashboard:

1. Go to **Settings** > **General** in your WordPress dashboard.
2. Make sure that both the **WordPress Address (URL)** and **Site Address (URL)** are set to `https://postmymeds.co.uk`.

If these settings are still using `http://`, WordPress will try to redirect requests to `https://`, and the web server might also try to do the same, creating a loop.

### 2. **Fix Redirection in `.htaccess` (for Apache)**

You might have a conflicting redirection rule. Here’s how you can adjust the `.htaccess` file to avoid the loop:

1. **Open your `.htaccess` file** (located in the root of your WordPress installation).
2. Make sure the **HTTPS redirect** rule is correctly placed at the top (just after `RewriteEngine On`), as shown below:

# BEGIN HTTPS Redirect
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
# END HTTPS Redirect

### 3. **Check the Web Server Configuration (for Nginx)**

If you're using **Nginx**, ensure there are no conflicting redirects. Here's the correct configuration for forcing HTTPS:

1. Open your Nginx configuration file (typically in `/etc/nginx/sites-available/default`).
2. Make sure you have a **separate HTTP to HTTPS redirect** block:

server {
    listen 80;
    server_name postmymeds.co.uk www.postmymeds.co.uk;

    return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl;
    server_name postmymeds.co.uk www.postmymeds.co.uk;

    # SSL settings (make sure these are correct for your SSL certificate)
    ssl_certificate /etc/nginx/ssl/postmymeds.crt;
    ssl_certificate_key /etc/nginx/ssl/postmymeds.key;

    # Your usual Nginx settings
}

This way, the HTTP server will handle the redirect, and the HTTPS server block will serve the actual site.

### 4. **Check for Plugins Causing Redirects**

Some WordPress plugins (such as **Really Simple SSL**) can cause conflicts when you've already configured server-level redirects. If you're using a plugin to handle SSL, try **deactivating** it and rely solely on your server’s `.htaccess` or Nginx configuration.

### 5. **Clear Cookies and Cache**

After making these changes:
1. Clear your **browser cookies** and cache.
2. Clear any **caching plugins** or **caching layers** like **Cloudflare** (if you're using it).

—

### Additional Notes:
– **Mixed Content**: After forcing HTTPS, make sure that all resources (images, scripts, etc.) are also loaded via `https://`. You can use a plugin like **Better Search Replace** to update URLs in your database.
– **SSL Certificate**: Ensure that your SSL certificate is correctly installed and active for both `postmymeds.co.uk` and `www.postmymeds.co.uk`.

—

By ensuring that both WordPress and your web server are properly configured, you should eliminate the **ERR_TOO_MANY_REDIRECTS** issue. Let me know how it goes!

### Steps to Force `https://` for Password Reset URLs

#### 1. **Ensure WordPress Generates URLs with `https://`**
WordPress determines the URL scheme (HTTP or HTTPS) based on the **WordPress Address (URL)** and **Site Address (URL)** in the settings.

1. Go to **Settings > General** in your WordPress dashboard.
2. Ensure both:
– **WordPress Address (URL)**: `https://postmymeds.co.uk`
– **Site Address (URL)**: `https://postmymeds.co.uk`

If these are already set correctly and you're still seeing `http://`, proceed to force the scheme programmatically.

—

#### 2. **Force `https://` in the Password Reset Email**
Use the `retrieve_password_message` filter to explicitly set the reset password URL scheme to `https`.

Add this code to your theme's `functions.php` file or a custom plugin:

add_filter('retrieve_password_message', function ($message, $key, $user_login, $user_data) {
    // Generate the reset password URL with HTTPS
    $reset_url = network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login));
    $reset_url = set_url_scheme($reset_url, 'https');

    // Replace any existing URL in the message with the forced HTTPS URL
    $message = preg_replace('/http://[^s]+/', $reset_url, $message);

    return $message;
}, 10, 4);

—

#### 3. **Check WordPress `home` and `siteurl` Options in the Database**
Sometimes, the settings in the database do not match what’s shown in the admin panel. Check and update the options directly in the database:

1. Access your database (via phpMyAdmin or a database client).
2. Run the following SQL query to verify the URLs:

SELECT option_name, option_value 
   FROM wp_options 
   WHERE option_name IN ('home', 'siteurl');

3. If either shows `http://`, update them to `https://`:

UPDATE wp_options 
   SET option_value = 'https://postmymeds.co.uk' 
   WHERE option_name = 'home';

   UPDATE wp_options 
   SET option_value = 'https://postmymeds.co.uk' 
   WHERE option_name = 'siteurl';

#### 4. **Force HTTPS Scheme Globally**
If WordPress is still generating `http://` URLs, force HTTPS for all URLs programmatically:

Add this code to your `functions.php` or a custom plugin:

add_filter('option_home', function ($url) {
    return set_url_scheme($url, 'https');
});

add_filter('option_siteurl', function ($url) {
    return set_url_scheme($url, 'https');
});

—

### 5. **Verify SendGrid Behavior**
After implementing the above changes, test again by requesting a password reset. Check the email to ensure:

– The password reset link starts with `https://`.
– SendGrid is no longer altering the link (since click tracking is disabled).

### Updated Solution: Modify the Reset Password URL with HTTPS and Allow Click Tracking

Add the following code to your theme's `functions.php` file or a custom plugin:

add_filter('retrieve_password_message', function ($message, $key, $user_login, $user_data) {
    // Generate the reset password URL with HTTPS
    $reset_url = network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login));
    $reset_url = set_url_scheme($reset_url, 'https');

    // Replace the existing URL in the message with the HTTPS URL
    $message = preg_replace('/http://[^s]+/', $reset_url, $message);

    return $message;
}, 10, 4);

—

### Explanation of the Code

1. **`network_site_url()`**:
– Generates the password reset URL based on your WordPress configuration.
– Ensures the correct domain and path are used.

2. **`set_url_scheme($reset_url, 'https')`**:
– Forces the reset URL to use `https://`.

3. **`preg_replace()`**:
– Replaces any existing `http://` link in the email message with the HTTPS version of the reset URL.

4. **SendGrid Click Tracking**:
– Once the email message is passed to SendGrid, click tracking will still apply to the updated `https://` link.

—

### Why This Works with SendGrid
SendGrid's click tracking works by modifying links in the email content and appending their tracking domain. By ensuring the URL sent from WordPress uses `https://`, SendGrid will apply its tracking to the correct HTTPS link.

—

### Testing Steps

1. **Enable Click Tracking in SendGrid**:
– Log in to SendGrid.
– Go to **Settings > Tracking > Click Tracking**.
– Ensure click tracking is enabled.

2. **Request a Password Reset**:
– Trigger a password reset request on your WordPress site.

3. **Check the Email**:
– Verify that the password reset link in the email starts with `https://` and has SendGrid's tracking applied.

Here’s how to properly override the reset password URL in this scenario:

—

### Correct Hook to Modify the URL
Instead of relying solely on `retrieve_password_message`, we need to directly filter the URL used for password resets. This can be done using the `lostpassword_url` filter. Additionally, ensure any occurrences of the `http://` URL in the email message are replaced with `https://`.

#### Complete Solution:
Add the following to your `functions.php` or a custom plugin:

// Force HTTPS for password reset URL
add_filter('lostpassword_url', function ($lostpassword_url, $redirect) {
    return set_url_scheme($lostpassword_url, 'https');
}, 10, 2);

// Modify the password reset email to include the HTTPS link
add_filter('retrieve_password_message', function ($message, $key, $user_login, $user_data) {
    // Generate the correct reset password URL
    $reset_url = network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login));
    $reset_url = set_url_scheme($reset_url, 'https'); // Force HTTPS

    // Replace the default URL in the email with the forced HTTPS URL
    $message = preg_replace('/http://[^s]+/', $reset_url, $message);

    return $message;
}, 10, 4);

—

### Why the Above Works with SendGrid Click Tracking
1. **`lostpassword_url` Filter**:
– Ensures that any link WordPress generates for the password reset process defaults to `https://`.

2. **`retrieve_password_message` Filter**:
– Ensures that the email body sent to SendGrid has the correct `https://` link, even if SendGrid's click tracking rewrites the URL with its tracking domain.

3. **SendGrid Click Tracking Behavior**:
– SendGrid will rewrite the `https://` URL to include its tracking domain. For example:
– Original: `https://postmymeds.co.uk/…`
– After tracking: `https://url9839.postmymeds.co.uk/…`

—

### Important Notes:
1. **Test Reset Links**:
– After implementing this code, trigger a password reset and verify the email contains the correct HTTPS reset link with the SendGrid tracking domain.

2. **Caching**:
– If you're using a caching plugin, clear the cache to ensure the updated filters are applied.

3. **Email Content**:
– Ensure the reset email doesn’t contain multiple URLs that could confuse SendGrid tracking.

4. **Additional Debugging**:
– If the URL still doesn't update to `https://`, it may be due to server-level redirects or incorrect `home`/`siteurl` settings in the WordPress database.

This approach ensures the link uses HTTPS while keeping SendGrid's click tracking enabled. Let me know if further adjustments are needed!

To address this issue, follow these advanced troubleshooting steps to force HTTPS **while keeping SendGrid click tracking enabled**:

—

### **1. Rewrite the URL in the Email Message with Hooks**

We need to ensure the `retrieve_password_message` filter explicitly injects the `https://` link **and handles SendGrid's behavior**.

#### Revised Hook Code

add_filter('retrieve_password_message', function ($message, $key, $user_login, $user_data) {
    // Generate the password reset URL with HTTPS
    $reset_url = network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login));
    $reset_url = set_url_scheme($reset_url, 'https'); // Force HTTPS

    // Replace all links in the message to ensure HTTPS is enforced
    $message = preg_replace('/http://[^s]+/', $reset_url, $message);

    return $message;
}, 10, 4);

—

### **2. Force HTTPS Scheme Globally in WordPress**
If SendGrid is rewriting URLs and defaulting to `http://`, you may need to enforce HTTPS for all URLs in WordPress programmatically.

Add this code to your `functions.php` or a custom plugin:

// Ensure all URLs in WordPress default to HTTPS
add_filter('option_home', function ($url) {
    return set_url_scheme($url, 'https');
});

add_filter('option_siteurl', function ($url) {
    return set_url_scheme($url, 'https');
});

—

### **3. Ensure SendGrid Recognizes HTTPS URLs**

SendGrid might use the original protocol provided by your web server or WordPress settings. To confirm HTTPS is enforced:

– **WordPress Settings**: Ensure the **WordPress Address (URL)** and **Site Address (URL)** in **Settings > General** are both set to `https://`.
– **Server Configurations**:
– In Apache `.htaccess` or Nginx configuration, ensure HTTPS is strictly enforced.
– Example `.htaccess` rule for Apache:

RewriteEngine On
    RewriteCond %{HTTPS} off
    RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

—

### **4. Check SendGrid Click Tracking Settings**

SendGrid rewrites links for tracking purposes. However, the rewritten links should retain the `https://` scheme. If they do not, confirm the following in your SendGrid account:

1. **Enable HTTPS Tracking**:
– Log in to SendGrid.
– Go to **Settings > Tracking > Click Tracking**.
– Ensure click tracking is enabled and supports `https://`.

2. **Verify Whitelabel Domain**:
– If you're using a custom domain for email tracking (e.g., `url9839.postmymeds.co.uk`), ensure it's properly configured with HTTPS.

—

### **5. Debugging and Testing**

1. **Verify the Generated URL**:
– Temporarily log the generated password reset URL to ensure it uses `https://` before being passed to SendGrid. Add this code:

add_filter('retrieve_password_message', function ($message, $key, $user_login, $user_data) {
         $reset_url = network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login));
         $reset_url = set_url_scheme($reset_url, 'https');
         error_log("Generated Reset URL: " . $reset_url); // Log the URL for debugging
         return $message;
     }, 10, 4);

– Check the **PHP error log** for the output.

2. **Inspect SendGrid Email Content**:
– After sending a password reset email, inspect the email's HTML source.
– Look for the password reset link. Confirm:
– Does it use the `https://` scheme?
– Is it rewritten by SendGrid? If yes, does the rewritten link start with `https://`?

—

### **Alternative Approach: Use `phpmailer_init` to Modify Email**

If the above filters don’t work, you can intercept the email message using the `phpmailer_init` hook and manually replace URLs in the email body before it is sent to SendGrid:

add_action('phpmailer_init', function ($phpmailer) {
    if (!empty($phpmailer->Body)) {
        // Replace http:// links with https:// links
        $phpmailer->Body = str_replace('http://', 'https://', $phpmailer->Body);
    }
});

—

### Recap
1. Use the `retrieve_password_message` filter to explicitly force `https://` in the reset link.
2. Ensure WordPress settings and server configurations enforce HTTPS globally.
3. Confirm SendGrid's click tracking supports HTTPS and your whitelabel domain is configured properly.
4. Debug by logging the generated URLs and inspecting email content.

Let me know the results after implementing these steps!

### **Final Solution: Use `phpmailer_init` to Ensure HTTPS Before Sending**

The `phpmailer_init` hook allows you to intercept the email before it's handed off to SendGrid. With this, you can enforce HTTPS in the email body and ensure it works with SendGrid's click tracking.

#### Code to Add

add_action('phpmailer_init', function ($phpmailer) {
    if (!empty($phpmailer->Body)) {
        // Use a regular expression to replace any http:// URLs with https://
        $phpmailer->Body = preg_replace('/http://(.*?)wp-login.php?action=rp&key=/', 'https://$1wp-login.php?action=rp&key=', $phpmailer->Body);
    }
});

—

### **Why This Should Work**
1. **Intercepts the Final Email**:
– Modifies the email body directly before it’s sent to SendGrid, ensuring the correct `https://` URL is present.

2. **Handles SendGrid Rewriting**:
– Since the URL is already `https://` in the email body, SendGrid’s tracking will retain the HTTPS scheme.

—

### **Steps to Implement**
1. Add the code to your `functions.php` file or a custom plugin.
2. Trigger a password reset email.
3. Check the email's HTML source to verify the password reset link starts with `https://`.

—

### **Debugging**
If the issue persists:
1. **Log the Final Email Body**:
Add this to log the modified email body for debugging:

add_action('phpmailer_init', function ($phpmailer) {
       if (!empty($phpmailer->Body)) {
           error_log("Final Email Body: " . $phpmailer->Body);
       }
   });

– Check your PHP error log to confirm the email body contains `https://`.

2. **SendGrid Click Tracking**:
– Ensure that your SendGrid account supports HTTPS for click tracking:
– **Settings > Tracking > Click Tracking**: Verify HTTPS is enabled.

3. **Inspect the Sent Email**:
– Use an email client or inspect the HTML of the received email to verify the reset link.

—

### **Fallback Solution: Custom Password Reset Email**
If none of the above works due to SendGrid's behavior, you can completely bypass the default password reset email and send your own email using `wp_mail` with the desired URL:

add_action('retrieve_password_message', function ($message, $key, $user_login, $user_data) {
    $reset_url = network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login));
    $reset_url = set_url_scheme($reset_url, 'https'); // Force HTTPS

    $custom_message = "Hi,nn";
    $custom_message .= "To reset your password, please click the link below:nn";
    $custom_message .= $reset_url . "nn";
    $custom_message .= "If you did not request a password reset, please ignore this email.n";

    return $custom_message;
}, 10, 4);

This overrides the default email entirely and ensures the correct link is used.
