Too Many Redirects Fix

—

### 1. **Update WordPress Site URL**
Ensure the site URL and WordPress URL are correctly set to use HTTPS.

#### a) Update via Admin Panel:
– Go to **Settings > General**.
– Update both **WordPress Address (URL)** and **Site Address (URL)** to start with `https://`.

#### b) Update via `wp-config.php`:
If you can't access the admin panel:
1. Open the `wp-config.php` file in your WordPress root directory.
2. Add these lines:

define('WP_HOME', 'https://yourdomain.com');
   define('WP_SITEURL', 'https://yourdomain.com');

### 2. **Check `.htaccess` File**
Ensure the `.htaccess` file has proper redirection rules. Here’s a basic setup for WordPress with HTTPS:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
RewriteBase /
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

### 3. **Check Plugin Conflicts**
A plugin conflict can also cause redirect loops:
– Temporarily disable all plugins by renaming the `wp-content/plugins` folder.
– If the issue resolves, re-enable plugins one by one to identify the culprit.

—

### 4. **Clear Cache**
– Clear your browser cache.
– If you’re using a caching plugin (e.g., WP Super Cache, W3 Total Cache), clear its cache and disable it temporarily.
– If your server uses caching (e.g., Nginx or Varnish), clear the server cache.

—

### 5. **Server Configuration**
#### a) Nginx:
Ensure HTTPS redirection is properly configured. Add the following to your Nginx configuration:

server {
    listen 80;
    server_name yourdomain.com www.yourdomain.com;
    return 301 https://yourdomain.com$request_uri;
}

#### b) Apache:
Ensure the `mod_rewrite` module is enabled:

sudo a2enmod rewrite
sudo systemctl restart apache2

### 6. **Cloudflare or Reverse Proxy**
If you're using a CDN or reverse proxy like Cloudflare:
– Ensure SSL is set to "Full" or "Full (Strict)" in the Cloudflare dashboard.
– Avoid enabling conflicting HTTPS redirection in both Cloudflare and WordPress.

—

### 7. **Debug the Issue**
If the issue persists, enable WordPress debugging:
1. Add this to `wp-config.php`:

define('WP_DEBUG', true);
   define('WP_DEBUG_LOG', true);

2. Check the `wp-content/debug.log` file for errors.

—

### 8. **Test and Verify**
– Use [Redirect Checker](https://www.redirect-checker.org/) to identify the redirect loop's origin.
– Test the site on an incognito browser or different device.

If the issue remains unresolved, share your `.htaccess`, server configuration, or any custom redirection settings you’ve applied for more specific guidance.
