How to Fix Common WordPress Errors

WordPress is a robust content management system, but like any software, it can have its share of issues. This guide will dive into how to fix common WordPress errors that you might encounter. By addressing these issues, you'll ensure a smooth and efficient website experience for both administrators and visitors.

Error Establishing a Database Connection

One of the most frequent problems users face is the "Error Establishing a Database Connection." This error indicates that WordPress is unable to communicate with the database. It can be caused by incorrect database credentials, a corrupt database, or a server issue.

How to Fix:

Check your wp-config.php file for correct database credentials.
Repair the database through phpMyAdmin.
Contact your hosting provider to ensure the server is running smoothly.

White Screen of Death (WSOD)

The White Screen of Death is another prevalent WordPress error. The whole screen turns white, showing no information. This can be due to a plugin conflict, theme issues, or exhausted memory limits.

How to Fix:

Disable all plugins and re-enable them one by one to identify the culprit.
Switch to a default WordPress theme.
Increase the PHP memory limit in the wp-config.php file.

404 Page Not Found Error

This error usually occurs when your site is unable to locate the requested page. This issue can be due to broken permalinks or a problem with the .htaccess file.

How to Fix:

Go to Settings → Permalinks and click Save Changes to refresh permalinks.
Edit the .htaccess file manually to ensure correct rules are in place.
