How to Enable Debug Mode in WordPress

6	(Optional) Define additional constants for further debugging. // Enable debug logging define( 'WP_DEBUG_LOG', true ); // Enable displaying of errors and warnings define( 'WP_DEBUG_DISPLAY', true ); // Enable logging of all queries and their execution time define( 'SAVEQUERIES', true );
7	Save the wp-config.php file.
