Hi @espsc_tecnologia This is a PHP warning message, which is generally only used by developers. In this case, it’s happening in a custom module Help Desk, which is created by members of the community. It’s not an actual error in the system, and shouldn’t cause issues with the function of Gibbon. We can let the developers know about the warning messages. In the meantime, on production systems, be sure your PHP error reporting levels only display errors and not warnings or notifications. You can do this through php.ini, or add the following to the bottom of your Gibbon config.php file: ini_set('error_reporting', E_ALL)
