What You Are Experiencing

Do any of these sound familiar?

When your WordPress site displays a message like “There has been a critical error on your website” or “The site is experiencing technical difficulties”, it means something fundamental has broken. This isn't a minor glitch; your site is likely inaccessible or severely impaired, impacting your business and reputation.

If any of these match, you are in the right place.

Your entire website is showing a “wordpress critical error on website” message to all visitors, meaning the wordpress critical error site completely down.

You are unable to log in to your WordPress admin area, facing a wordpress critical error can't login to admin situation.

You're receiving critical error email every day from WordPress, even if the site appears to be working intermittently.

The error message specifically states “wordpress critical error please check your site email” for details, but the email might be vague or overwhelming.

You've recently updated a plugin, theme, or WordPress core, leading to a WordPress Fatal Error After Plugin, Theme or Core Update.

Your site is slow, unresponsive, or displaying a WordPress Fatal Error — Memory Size Exhausted message before the critical error.

Root Cause

Why this happens

A wordpress critical error on website typically indicates a fatal PHP error that prevents WordPress from loading correctly. This can be triggered by a variety of factors, often related to recent changes or resource limitations.

Common causes include conflicts between plugins or themes, especially after updates. A poorly coded plugin or theme can introduce incompatible code, leading to a WordPress PHP Fatal Error — Undefined Function, Cannot Redeclare, Class Not Found. Insufficient PHP memory limits or execution time can also cause the site to crash, as seen with WordPress Maximum Execution Time, Headers Already Sent and Output Buffer Errors.

Sometimes, the error is a result of an incompatible PHP version, particularly after a server upgrade or a WordPress Fatal Error After PHP 7 to PHP 8 Upgrade. Database corruption or issues with core WordPress files can also lead to a complete site failure, displaying the generic "wordpress there has been a critical error on your website" message.

Even if your site appears fine, you might be receiving critical error email every day due to background processes or specific page loads triggering a minor, but logged, issue. For these cases, see WordPress Critical Error Emails — Site Looks Fine But Still Getting Errors.

Work through these in order. Each step is safe unless noted otherwise.

Check Your Site Admin Email for Details

WordPress often sends a detailed email to the site administrator's email address when a critical error occurs. This email typically contains specific information about the plugin, theme, or file causing the problem, along with a stack trace. Look for the subject line "WordPress Critical Error" or similar. This is the first place to find clues about why your site is experiencing technical difficulties.

Disable All Plugins via FTP

Many critical errors stem from plugin conflicts or faulty plugin code. Access your site via FTP or your hosting file manager. Navigate to wp-content/plugins/. Rename the plugins folder to something like plugins_old. This will deactivate all plugins. Try accessing your site and admin area. If the error resolves, reactivate plugins one by one by renaming the folder back to plugins and then deactivating them individually from the WordPress admin until you find the culprit. Be aware that renaming the folder will temporarily break site functionality reliant on plugins.

wp-content/plugins/

Switch to a Default Theme via FTP

If disabling plugins didn't work, your theme might be the issue. Via FTP, navigate to wp-content/themes/. Rename your active theme's folder (e.g., mytheme to mytheme_old). WordPress will automatically fall back to a default theme like Twenty Twenty-Three if it exists. If the error clears, your theme is the problem. You may need to reinstall it or contact the theme developer.

wp-content/themes/

Enable WordPress Debugging

To get more specific error messages instead of the generic critical error screen, enable WordPress debugging. Connect via FTP and edit your wp-config.php file in the root of your WordPress installation. Add or modify the following lines. This will display errors on your site and log them to a file. Remember to disable debugging once you've gathered the information, as it can expose sensitive details.

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );
@ini_set( 'display_errors', 0 );

If none of these steps resolved it, this is where professional help saves time.

Attempting to fix a wordpress critical error on website can be time-consuming and frustrating, especially if you're not familiar with server environments or debugging WordPress code. When these initial steps don't yield results, it's often a deeper issue requiring expert diagnosis.

FAQ

Common questions

What does 'There has been a critical error on your website' mean?

This message indicates a fatal PHP error that has prevented WordPress from loading correctly. It's a generic message designed to prevent visitors from seeing raw error code, but it means your site is down or severely broken. It often points to a problem with a plugin, theme, or an issue with your server's PHP configuration.

Can I fix a 'wordpress critical error on website' myself?

Sometimes, yes. Basic troubleshooting like checking your admin email for specific error details, disabling plugins via FTP, or switching to a default theme can resolve simpler critical errors. However, if the issue is more complex, involving server configurations, database corruption, or intricate code conflicts, professional help is usually faster and safer to prevent further damage.

Why am I 'receiving critical error email every day' but my site looks fine?

If your site appears functional but you're still getting critical error emails, it means an error is occurring in the background or on specific, less-frequented pages. These might be cron jobs, API calls, or errors triggered by certain user interactions. While less urgent than a completely down site, these errors indicate underlying issues that should be addressed to maintain site health and prevent future outages.
