WordPress is a powerful platform, but like any software, it can encounter issues. Knowing how to troubleshoot common WordPress errors will save time and keep your site running smoothly.

This is one of the most common WordPress issues. It usually occurs due to a corrupted .htaccess file, plugin conflicts, or exhausted memory limits.

• Solution: Rename the .htaccess file to create a new one by going to Settings > Permalinks and saving. If that doesn’t work, deactivate all plugins and reactivate them one by one to identify conflicts.

A completely blank screen with no error message, this often happens when a theme or plugin has a conflict, or you’ve exhausted your PHP memory limit.

• Solution: Increase your memory limit in the wp-config.php file by adding:

define( 'WP_MEMORY_LIMIT', '64M' );

You can also try disabling themes or plugins through FTP if you can’t access the admin dashboard.

Sometimes, WordPress posts return a 404 error, while the rest of the site works fine.

• Solution: Go to Settings > Permalinks and click Save Changes to reset permalinks. If the issue persists, review your .htaccess file and ensure it contains the correct rewrite rules.

This occurs when your server is overloaded or can't handle requests due to limited resources.

• Solution: Deactivate resource-intensive plugins, increase your PHP memory limit, or upgrade your hosting plan.

This error occurs when WordPress is unable to connect to your database due to incorrect credentials or a corrupted database.

• Solution: Check your wp-config.php file for the correct database credentials. If the information is correct, you can try repairing the database by adding this line to wp-config.php

define( 'WP_ALLOW_REPAIR', true );

• Then visit the repair page by going to yoursite.com/wp-admin/maint/repair.php.

When WordPress updates fail, your site can get stuck in maintenance mode, displaying the message "Briefly unavailable for scheduled maintenance."

• Solution: Delete the .maintenance file from your site’s root directory via FTP.

This typically happens when you’ve edited your WordPress files and accidentally introduced a code syntax error.

• Solution: Access your site via FTP, locate the file with the error, and correct the syntax (such as missing punctuation or misplaced code).

Sometimes, WordPress fails to upload images, either due to permissions problems or file size limitations.

• Solution: Ensure your wp-content/uploads folder has the correct permissions (755 or 775). You can also try increasing your maximum upload file size by editing your php.ini file.

This issue can happen due to plugin conflicts or incorrect login credentials.

• Solution: Reset your password using the “Lost your password?” link or update it via phpMyAdmin. If a plugin is causing the issue, deactivate all plugins through FTP and try logging in again.

Occasionally, automatic updates for WordPress can fail, leaving your site broken.

• Solution: Manually update WordPress by downloading the latest version, overwriting your files (except wp-content), and running the database update.

While encountering WordPress errors can be frustrating, most can be resolved with simple troubleshooting steps. Identifying the root cause of the problem is essential, and keeping backups ensures you can restore your site if needed.
