220.127.116.11. Enabling Debug Mode in Drupal
Openup config file site using the built-in editor filemanager or any FTPclient and add the line to it:
$config['system.logging']['error_level'] = 'verbose';
After identifying the causes of errors on the site and eliminating them, it is recommended to disable the debug mode. To do this, it is enough to delete the added line.
