I am running dnn 4.06.02 with forums 4.4.03.  Up until now it is been working flawlessly.  Now when I try and create a new post on any topic I get the following error.  I searched the forums and found things similar but not exactly the same.  Any suggestions?

The same issue, just upgraded to Dotnetnuke 04.08.00 and now one user can´t create new posts... The user are administrator. Other administrators can publish new messages without problems

Any ideas are welcome
