WordPress is a robust and popular platform, but like any other system, it can occasionally present users with error codes. These error codes provide important clues about what went wrong on your website, helping you troubleshoot and resolve the issues. This blog will cover common WP error codes, what they mean, and how you can fix them.
What Are WP Error Codes?
WP error codes are messages that WordPress generates when something goes wrong with your website. These errors can be caused by various factors, including themes, plugins, server settings, or even corrupted files. Each error code indicates a specific problem, helping you to diagnose and resolve it effectively.
Common WP Error Codes and Their Fixes
1. 500 Internal Server Error
This is one of the most common WordPress errors. It usually indicates a server-side problem, which corrupted .htaccess files, plugin conflicts, or exhausted PHP memory can cause.
How to Fix:
- Step 1: Check the .htaccess file. Rename it and create a new one with default WordPress rules.
- Step 2: Deactivate all plugins and reactivate them one by one to find the problematic plugin.
- Step 3: Increase the PHP memory limit in your wp-config.php file.
2. 404 Error – Page Not Found
The 404 error means the server couldn’t find the requested page. This usually occurs when the URL is incorrect or the page has been moved or deleted.
Common Causes:
-
Incorrect or broken URLs.
-
Deleted or renamed content.
-
Misconfigured permalinks.
How to Fix a 404 Error:
-
Step 1: Go to Settings > Permalinks in the WordPress dashboard and click “Save” to refresh the permalink settings.

-
Incorrect file permissions.

Security plugins blocking access.

-
Step 3: Reset your .htaccess file by renaming it and creating a new one with default WordPress rules.

Incorrect login credentials.

Browser cache or cookie issues.
How to Fix a 401 Error:

Step 1: Clear your browser cache and cookies, then try logging in again.

- Step 3: Disable WordPress maintenance mode if it is accidentally stuck.
