Apologies. Posted about this issue some time ago with specifics, or "sorta" specifics. Basically any attempt to edit an existing setting like queues, notifications, etc gets a 403 access denied error. Front end appears to work fine. I have disabled mod_security for the OTRS virtual servers for the time being.
OTRS version is 3.0.7
Here's my mod_security recipe

Nothing???? Really???? No one has successfully used mod_securty with OTRS?
Well, why not look at the logs to see what is blocked and why?
