I can force refresh my page and it comes back, but this is becoming pretty ridiculous.

My PBX is Vanilla Asterisk, FOP2 is running on Ubuntu 13.04 server and my MySQL database is on another Ubuntu 13.04 server. The FOP2 server can see the MySQL database with no trouble.

Every hour or so, (I haven't timed it because I'm too busy) if I click on the phonebook icon in FOP2, I get the "you do not have permission..." message.

I then refresh my browser and bam! it works again.

Ideas?

Yes, i had the same. I solved it very easy - just cut

if($allowed <> "yes") {
die("You do not have permissions to access this resource.");
}

from phonebook.php and recordings.php and Bam ! - everythins Ok !

Best regards,
Sergio.

I guess that works, considering all my users should have access.
