I've been trying to nail down a working setup of FOP2 for the better part of two weeks now, and I think it's time to ask for some help.
Ideally, this will be running Debian 8 in a VM, with asterisk and scarcely anything else. In other words, the "LAMP" stack is there for no other reason than FOP2, and is of default configuration. I am editing my own users, groups, and button. However, I have also tried to do use FOP2 admin--which, for me, also appears to be broken.
The most tangible problem I have is that of "You do not have permission to access this resource", for each: the Recordings, Contacts, and Call History. Also, the login page reloads frequently. I've seen the Trixbox, PHP Sessions and FOP2 post, and it would seem I indeed have a problem with sessions but I am at a loss as to how to configure on a vanilla system.
I don't believe it's actually a permissions problem, because I've granted "all" of them, like so...
