We've tested our application on several computers and on one of them we got error message:
"A processing error has occured:
User lacks required permission.
The missing permission is 'SAL_ADM_Service'
Error location: null"
The problem is, user had that permission. As I said it happened only once, so it's hard to replay situation...
Have you ever got this error?
Another unique one, was something with 'template not found' - again - happened just once.
P.S. Was tested on Linux, FF3
For best results, use the Firefox browser..
