WP Admin Slow PHP 8.3

—

### **1. Check PHP Compatibility**
Ensure all installed plugins, themes, and the WordPress version support PHP 8.3:
– Visit the plugin and theme pages in `wp-admin` or their respective websites to confirm compatibility.
– Update WordPress to the latest version if not already done.
– Update all plugins and themes to their latest versions.

—

### **2. Enable WordPress Debugging**
Turn on debugging to identify errors causing slowness:
1. Edit the `wp-config.php` file and add or update the following:

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

2. Access `wp-admin` to reproduce the issue.
3. Check the debug log in `wp-content/debug.log` for errors or warnings.

—

### **3. Profile Slow Queries**
Analyze database queries that may be causing slowness:
– Install the **Query Monitor** plugin.
– Navigate through `wp-admin` and observe slow queries or scripts in the Query Monitor panel.
– Focus on plugins or themes responsible for long-running queries.

—

### **4. Test Plugins and Themes**
Identify the source of slowness by disabling plugins:
1. Deactivate all plugins and test `wp-admin`.
2. Reactivate plugins one by one to pinpoint the culprit.
3. Switch to a default theme (e.g., Twenty Twenty-Four) to rule out theme-related issues.

—

### **5. Review the Error Logs**
Check your server's PHP error logs for compatibility-related errors:
– Log files are typically located in `/var/log/php/` or a similar directory, depending on your hosting setup.

—

### **6. Optimize the Admin Panel**
Apply general optimizations:
– Clear cache using plugins like **WP Super Cache** (which you're already using).
– Optimize the database using plugins like **WP-Optimize**.
– Limit admin-side resource-heavy plugins, such as WooCommerce reporting tools, which may perform slow queries.

—

### **7. Check PHP Configuration**
Review the PHP settings to ensure optimal configuration:
– Verify memory limits:

memory_limit = 256M

– Enable OPcache for PHP:

opcache.enable=1
  opcache.memory_consumption=128
  opcache.max_accelerated_files=10000

—

### **8. Monitor Server Resources**
Use tools like `htop` or `top` to monitor server CPU and memory usage when accessing `wp-admin`. A spike in usage might indicate server resource limits or a poorly optimized query.

—

### **9. Roll Back PHP Version Temporarily**
If the issue persists and the compatibility issue is not easily resolvable:
– Downgrade to PHP 8.2 or 8.1 temporarily.
– Investigate compatibility updates with plugins/themes while maintaining performance.

—

### **10. Focus on WooCommerce Plugins**
Since you’re using WooCommerce:
– The **Customer Order CSV Export plugin** has been noted to cause performance issues. If it's still active, try deactivating it or optimizing its database queries.
– Check WooCommerce database tables for excessive data accumulation.

—

### **1. Clear Cache**
Start by clearing all caches:
– **Plugin Cache:** Clear cache from plugins like WP Super Cache, W3 Total Cache, or others you use.
– **Browser Cache:** Clear your browser's cache or test in incognito mode.
– **Server Cache:** If your host has server-side caching, clear it via your hosting dashboard.

—

### **2. Check Default Language Setting**
Even after WPML is removed, the default language in your WordPress setup might still be set to German:
1. Go to **Settings > General** in your WordPress dashboard.
2. Check the "Site Language" setting. Set it to **English (United States)** or your desired English locale.
3. Save changes.

—

### **3. Inspect Database for Residual WPML Data**
WPML stores multilingual data in custom database tables and sometimes leaves residual data after removal:
1. Access your database using phpMyAdmin or a similar tool.
2. Look for tables or options with names like `wp_icl_translations`, `wp_icl_string_translations`, etc., and confirm they contain no essential data before deletion.
3. Use a database cleanup plugin like **WP Sweep** or **Advanced Database Cleaner** to remove orphaned entries.

—

### **4. Check Page Content**
If the content itself was modified to German while WPML was active:
1. Go to **Pages** in `wp-admin`.
2. Edit the affected pages to verify if the German content is stored there.
3. Restore English content from backups if available.

—

### **5. Scan Permalinks**
After removing WPML, permalinks might still have language-related structures:
1. Go to **Settings > Permalinks**.
2. Save the settings (without making changes) to flush the rewrite rules.
3. Test if the pages are now correctly displaying English.

—

### **6. Check Theme and Plugins for Multilingual Residue**
Some themes and plugins integrate with WPML and may still serve German content:
1. Deactivate plugins one by one to identify any causing the issue.
2. If your theme has multilingual settings, check its configuration or reset them.

—

### **7. Restore Backups**
If the above steps don’t resolve the issue:
1. Restore a backup taken before installing WPML or before deleting it.
2. Carefully remove WPML again using the steps mentioned in WPML’s official guide.

—

### **8. Consider Reinstalling WPML Temporarily**
Reinstall WPML to cleanly remove all translations:
1. Install WPML and activate it.
2. Go to **WPML > Support > Troubleshooting** and use the cleanup tools to:
– Remove German translations.
– Reset WPML settings.
3. Deactivate and uninstall WPML again.
