Hi there. A customer recently complained that one specific ticket cannot be opened, it comes up with the generic error screen in service.

As you can see, i've tried to activate print exceptions on screen at the debug menu, but it just tells me the exception is classified. I've checked the debug log, and i've checked the log folder on the server (in the customer service folder)
There are no logs of this event - i can get to the edit screen, but get the same message when i try to save.
The customer is using a custom version of View Ticket, but the standard view ticket screen (without alterations) has been tried as well, same result.
So where can i find the log message, that im told is logged, so i can see what is wrong??
Thanks
