Introduction
WordPress is a powerful platform used by millions worldwide, but sometimes users encounter errors that can disrupt their workflow. Understanding how to fix these common issues can save time and maintain your site’s functionality. This guide will cover several frequent WordPress errors and their solutions.
404 Page Not Found Error
The 404 error typically occurs when the server cannot find the requested page. It usually happens due to broken links or incorrect URL configurations.
Solution
Check Permalinks: Navigate to Settings > Permalinks in your WordPress dashboard. Simply click Save Changes to refresh the permalinks. This process can often resolve errors resulting from URL issues.
Modify .htaccess File: Access your site via FTP and locate the .htaccess file. Ensure it includes the default WordPress code needed for proper URL handling.
Internal Server Error
Also known as a 500 error, this issue is generally server-side and can result from a faulty plugin or theme.
Solution
Increase PHP Memory Limit: Sometimes, increasing your PHP memory limit can resolve this error. Edit your wp-config.php file and add:
“`php
define(‘WP_MEMORY_LIMIT’, ’64M’);
“`
Deactivate Plugins and Themes: Temporarily disable all plugins by renaming the plugins folder via FTP. Once the issue is resolved, reactivate plugins one by one to identify the problematic one.
Check for Corrupted .htaccess File: Rename your .htaccess file and try accessing your site. If the error is fixed, regenerate the file by saving the Permalinks settings in the admin dashboard.
White Screen of Death
The White Screen of Death (WSOD) leaves a page blank, often without error messages, making troubleshooting difficult.
Solution
Enable Debugging: Add the following lines to your wp-config.php file:
“`php
define(‘WP_DEBUG’, true);
define(‘WP_DEBUG_LOG’, true);
“`
This will allow error logging, which can aid in identifying the root cause.
Increase PHP Memory Limit: As with the 500 error, increasing the memory limit may help resolve the WSOD.
Check for Theme/Plugin Conflicts: Switch to a default theme like Twenty Twenty-One. Disable all plugins and then reactivate them one by one to identify if a single plugin causes the issue.
Error Establishing a Database Connection
This error appears when WordPress cannot connect to the database server, often due to incorrect database credentials.
Solution
Verify Database Credentials: Open the wp-config.php file and ensure the database name, username, password, and host are correct:
“`php
define(‘DB_NAME’, ‘database_name_here’);
define(‘DB_USER’, ‘username_here’);
define(‘DB_PASSWORD’, ‘password_here’);
define(‘DB_HOST’, ‘localhost’);
“`
Repair Database: Add this line to wp-config.php to enable automatic database repair:
“`php
define(‘WP_ALLOW_REPAIR’, true);
“`
Visit http://www.yoursite.com/wp-admin/maint/repair.php to repair your database, then remove the line afterward to secure your site from unauthorized access.
