You can enable WordPress debug without displaying the messages publicly to the site visitors.
You can enable WordPress debug in WordPress by adding:
define('WP_DEBUG', true); define('WP_DEBUG_LOG', true); define( 'WP_DEBUG_DISPLAY', false ); ini_set('error_reporting', E_ALL);
to the wp-config.php file.
WordPress debug messages are logged without displaying to your site visitors. After the issue is resolved, you can turn debugging off by chaninging the line define(‘WP_DEBUG’, true) to define(‘WP_DEBUG’, false);
You can find wp-config.php in your WordPress directory and copy and paste the 3 lines above in that file.
Please make sure none of the lines above are repeated in the file.
You can then find the debug.log file in the WordPress wp-content directory.
