I have a problem when you log in the system only allows 4 people to enter (Agents or Users), if you want to enter a fifth person it no longer works and shows a "fatal error contact system administrator" message.
Does not allow more than 5 users to enter
Thread restored.
I don't think I've ever heard of such a thing. Are you sure you're using an official osTicket package?
Cheers.
