To fix the Internal Server Error (500 Error) on your WordPress blog, follow these detailed steps:
Step 1: Backup Your Website
Before making any changes, create a complete backup of your WordPress site, including files and the database.
Step 2: Check the .htaccess File
1. Access Your Site via FTP or Hosting File Manager
• Use an FTP client like FileZilla or your hosting control panel’s file manager.
2. Locate the .htaccess File
• It’s in the root directory where wp-content, wp-admin, and wp-includes folders are.
3. Rename the File
• Rename .htaccess to .htaccess_old.
4. Check Your Site
• Visit your website to see if the issue is resolved.
5. Regenerate .htaccess
• If the site works, regenerate .htaccess:
• Go to WordPress Dashboard > Settings > Permalinks.
• Click Save Changes without making any adjustments.
Step 3: Increase PHP Memory Limit
1. Edit wp-config.php
• Access the root directory using FTP or File Manager.
• Open wp-config.php and add the following line just before /* That’s all, stop editing! Happy publishing. */:
define(‘WP_MEMORY_LIMIT’, ‘256M’);
2. Save and Upload the File.
• Check your website again.
Step 4: Deactivate Plugins
1. Access the WordPress Plugin Folder:
• Go to wp-content/plugins using FTP or File Manager.
2. Rename the Plugins Folder:
• Rename the plugins folder to something like plugins_old.
• This disables all plugins.
3. Check Your Site:
• If the site works, the issue is caused by a plugin.
4. Reactivate Plugins One by One:
• Rename the plugins_old folder back to plugins.
• Activate plugins one at a time through the WordPress dashboard to find the culprit.
Step 5: Switch to a Default Theme
1. Access wp-content/themes Folder
• Rename your active theme folder to something like theme_old.
2. Activate a Default Theme Automatically
• WordPress will switch to a default theme like Twenty Twenty-Three.
3. Check Your Site:
• If this fixes the issue, your theme might be causing the error. Consider updating or reinstalling it.
Step 6: Reinstall WordPress Core Files
1. Download a Fresh Copy of WordPress
• Go to wordpress.org and download the latest version.
2. Extract Files:
• Extract the files to your computer.
3. Upload Core Files via FTP:
• Upload everything except the wp-content folder and wp-config.php file.
• Allow the system to overwrite core files.
4. Check the Site Again.
Step 7: Check Server Error Logs
1. Access Hosting Control Panel:
• Look for an Error Logs section or ask your web hosting support to check error logs.
2. Fix Any Server-Side Errors:
• If logs point to server-side issues, contact your web hosting provider.
Step 8: Contact Your Web Host
If none of the above steps work, contact your hosting provider’s support team. They can help troubleshoot server-related problems.
