How to Debug WordPress Errors

To debug errors in WordPress, follow these steps:

1. Access the wp-config.php File
   Open the wp-config.php file located in the root directory of your WordPress installation.
2. Enable Debugging
   Find the following line in the file:

   define('WP_DEBUG', false);

Change it to:

   define('WP_DEBUG', true);

3. Add Additional Debugging Configurations
   Right below the define('WP_DEBUG', true); line, add the following lines:

   define('WP_DEBUG_LOG', true);
   define('WP_DEBUG_DISPLAY', false);
   error_log('Memory usage: ' . memory_get_usage());

4. Check the Debug Log
   After these steps, WordPress will log errors to the file located at wp-content/debug.log. This file will continuously grow as errors are logged.
5. Restore Configurations After Debugging
   Once debugging is complete, revert the wp-config.php settings to their original state to stop the debug log from growing indefinitely:

   define('WP_DEBUG', false);

This method helps you diagnose WordPress issues while keeping error details logged in a secure place (debug.log), without displaying them publicly on the website.
