Problem:
You see this message when trying to log in to your WordPress admin:
“There has been a critical error on this website. Please check your site admin email inbox for instructions.”
Most Common Cause:
Usually, this means one of your plugins has a problem.
How to Fix It (Step-by-Step):
1. Open File Manager or FTP
-
Login to your hosting account or use an FTP software (like FileZilla).
-
Go to your WordPress folder.
-
Open the folder: wp-content.
2. Turn Off All Plugins
-
Find the plugins folder.
-
Rename the folder from plugins to plugins.disable.
-
This will turn off all plugins.
3. Try to Login Again
-
Go to your WordPress admin login page.
-
If it works now, the problem is one of the plugins.
4. Find the Problem Plugin
-
Rename plugins.disable back to plugins.
-
Open the plugins folder.
-
Now, rename each plugin folder one by one (example: change plugin-name to plugin-name.disable).
-
After each rename, try to log in to WordPress.
-
When you can log in, the last plugin you renamed is the one causing the problem.
5. What to Do Next
-
You can delete the bad plugin, update it, or contact the plugin support.
