Investigating The Cause
To understand how to fix the ‘WordPress: There has been a critical error on this website’ error, you first need to know what is causing it.
1. Plugin or Theme Conflicts:

Resolving Plugin or Theme Conflicts
To solve the ‘WordPress: There has been a critical error on this website’ due to plugin or theme conflicts, you can follow these steps:
1. Plugin Troubleshooting:
If you suspect a plugin is causing the problem, try deactivating all plugins. If the error disappears, then one of the plugins is indeed the culprit.

Addressing Memory Limit Issues
If the ‘WordPress: There has been a critical error on this website’ message is due to memory limit exhaustion, you can increase the memory limit by editing the wp-config.php file.

Fixing Database Connection Problems
If the problem is a database connection error, the ‘WordPress: There has been a critical error on this website’ message might be accompanied by another message like “error establishing a database connection.” In this case, you should check your wp-config.php file to ensure your database details are correct.
