Troubleshooting Common WordPress Errors
WordPress is a powerful and versatile platform, but like any software, it can sometimes encounter issues. This guide will help you troubleshoot some of the most common WordPress errors.
1. White Screen of Death
The White Screen of Death (WSOD) is one of the most common and frustrating errors in WordPress. It usually results from a PHP error or a memory limit exhaustion.
- Solution:
- Enable Debugging: Add the following line to your wp-config.php file to enable debugging:
define('WP_DEBUG', true); - Increase Memory Limit: Add this line to your wp-config.php file:
define('WP_MEMORY_LIMIT', '64M'); - Deactivate Plugins: Deactivate all your plugins and reactivate them one by one to find the culprit.
2. Internal Server Error
An Internal Server Error (500) is a generic error message indicating something went wrong on the server.
- Solution:
- Check .htaccess File: Rename your .htaccess file to .htaccess_old and refresh your site to see if the error is resolved.

define('WP_MEMORY_LIMIT', '64M');to your wp-config.php file. - Re-upload Core Files: Replace the wp-admin and wp-includes folders with fresh copies from a new WordPress download.

define('WP_ALLOW_REPAIR', true);to your wp-config.php file and visithttp://yourwebsite.com/wp-admin/maint/repair.php. - Contact Hosting Provider: If the issue persists, contact your hosting provider to check if the database server is down.
4. 404 Not Found Error
This error usually occurs when a post or page is not found. It is often caused by issues with permalink settings.
- Solution:
