I wonder if you tell me how i can enable phpfox v4.5 extensions section to add new module to phpfox! I am using phpfox v4.5 nulled and i'm trying to write new module for that, but unfortunately i can not find extension section like before.
In PHPFOX v4.x there is disable extension from the admincp. But you can create custom app which is like module by refer below link.
