This is a diagnostic and error reporting feature for websites built with a popular content management system. It is designed for site administrators and developers to handle unexpected failures that prevent a site from loading. When a critical error occurs, this system intervenes to display a user-friendly message instead of a confusing technical failure, while logging the details needed for troubleshooting.

• Automatic Error Detection: The system monitors for fatal PHP errors, plugin conflicts, or theme issues that would normally cause a blank white screen or a server error.
• User-Friendly Frontend Message: Site visitors see a generic error message, which prevents exposure of sensitive technical details and maintains a professional appearance during an outage.
• Detailed Error Logging: For administrators, the tool records specific error details, including the error type, file, and line number, in the site's debug log. This information is crucial for identifying the root cause.
• Safe Mode Access: In many cases, the error screen still allows administrators to log into the site's backend dashboard. From there, they can deactivate problematic plugins or themes to restore basic functionality.
• Development Environment Control: The behavior of this error handler can be configured. In a development setting, it can be set to display full error details directly on the screen to speed up debugging.
