In the realm of WordPress, encountering an error message stating "There has been a critical error on this website" can be a disheartening experience. However, as a WordPress site owner in 2023, you need not despair. This article provides a detailed, step-by-step guide to troubleshooting and resolving this critical error, effectively restoring your website's functionality.

Understanding the Critical Error Issue

Before diving into solutions, it's essential to grasp what this critical error signifies. Essentially, it's WordPress's way of saying that something has gone awry with your PHP code. This issue can stem from various sources, such as a problematic plugin, a theme conflict, or an unsuccessful WordPress update.

Identifying the Issue

Identifying the culprit behind the error is the first step in rectifying it. Debugging mode in WordPress is a helpful tool to diagnose the issue. You can enable it by adding the following code to your 'wp-config.php' file:

define( 'WP_DEBUG', true );

After enabling debugging, the error message will provide more specific information about the issue, such as highlighting a problematic plugin or theme.

Fixing the Issue

Deactivating Plugins

If the error points towards a plugin, deactivating all plugins will help. Access your site's server using FTP (File Transfer Protocol), navigate to '/wp-content/', and rename the 'plugins' folder. This deactivates all plugins, and if the site works, one of your plugins was the problem. You can then rename the folder back to 'plugins' and activate each one by one to pinpoint the problematic plugin.

Switching Themes

If a theme conflict is causing the error, switch to a default theme. In your FTP server, navigate to '/wp-content/themes/', find your current theme, and rename the folder. WordPress will default to a pre-installed theme, and if your site works, the issue was with your theme.

Updating WordPress Core

An unsuccessful WordPress update can also cause a critical error. In such cases, manually updating WordPress via FTP can resolve the issue. Download the latest WordPress version, extract the files, and upload them to your server, overwriting the existing files.

Prevention Tips

To prevent such errors in the future:

Regularly back up your website to ensure you can quickly restore it if anything goes wrong.

Keep your WordPress core, themes, and plugins updated.

Use a staging site to test updates before applying them to your live site.


Resolving the critical WordPress error of 2023 requires patience and a systematic approach. By following these steps, you can identify and rectify the issue efficiently. If you're still facing problems, consider reaching out to WordPress support or professional services for further assistance. Remember, regular site maintenance and backups are key to preventing such errors, ensuring a smooth-running, SEO-optimized website.
