Debug is a free utility tool designed for WordPress that assists users in identifying errors within their websites. This plugin allows users to edit the wp-config.php file to enable error reporting, making it easier to diagnose issues. Additionally, it offers the functionality of sending email notifications for any runtime bugs encountered in the WordPress CMS. This feature is particularly useful for website administrators looking to maintain a smooth user experience.

The plugin operates by rewriting the wp-config.php file utilizing the error_log function in PHP. However, users should be aware that if they lack file write permissions, the plugin may not function as intended. It is also recommended to create a backup of the wp-config.php file before applying any changes through the plugin settings, ensuring that users can restore their original configuration if necessary.
