[otrs] faq on 2.4.4

Hello OTRS users, I'm having some problems trying to get the FAQ module to work on OTRS 2.4.4. The install went fine, it created the faq and faq_admin groups and I can see the icon on the toolbar. I've added my user to both the faq and faq_admin group with full permissions, but when I try to add categories or even create a faq it tells me "Access Denied" with the message "insufficient permissions". Nothing useful shows up in the log. Any ideas on how to get it working? did I miss a step? Already tried logging out and back in, restarting apache and otrs. Thanks, Giordano
