Introduction to WordPress Error Troubleshooting

Experiencing errors on your WordPress site can be frustrating. However, most issues are common and can be solved with a systematic approach. Here, we’ll discuss some frequent WordPress errors and how to resolve them effectively.

Error Establishing a Database Connection

This error often occurs when WordPress is unable to connect to the database. Check your wp-config.php file to ensure that your database credentials are correct. Sometimes, the issue might be with the server itself, and in such cases, contacting your hosting provider is advisable.

White Screen of Death (WSOD)

The infamous WSOD can be caused by exhausted memory limits or problematic plugins. Increasing the PHP memory limit in your wp-config.php file can help. Additionally, you can debug by deactivating all plugins and reactivating them one by one to identify the culprit.

Internal Server Error

This generic error can be addressed by checking for corrupted .htaccess files or increasing PHP memory limits. A useful plugin for deep troubleshooting in such scenarios is WP Debugging, which can provide deeper insights into the underlying issues.

These errors typically occur when the rewrite rules in the .htaccess file get messed up. Fixing it is usually as simple as going to Settings > Permalinks in the WordPress admin and just clicking ‘Save Changes’ to reset the permalinks structure.
