I tried to upgrade the IfffServer to 3.6.19 and before I could do that I had to update Common to 3.4.54 and now I am getting:
Warning: require_once(/var/www/html/modules/Common/TraitModule.php): Failed to open stream: No such file or directory in /var/www/html/modules/EasyAdmin/Module.php on line 33
Fatal error: Uncaught Error: Failed opening required ‘(/var/www/html/modules/TraitModule.php’ (include_path=‘.:/usr/share/php’) in /var/www/html/modules/EasyAdmin/Module.php on line 33
Line 33 of EasyAdmin has always been require_once dirname(__DIR__) . '/Common/TraitModule.php';, so it is looking inside Common, and it is the same for all new modules i manage. If it is not, it should be related to a custom or out-of-date module.
In your case, find the module that uses ‘/TraitModule.php’. Or copy it at the root of the directory “modules”.
