I received the following error when I tried to mark all posts as read for CAM forum:
Unable to verify referring url. Please go back and try again.
I got the same message when trying to set an old topic as sticky.
I moved it to a different forum and then could do it.
http://ducatimonsterforum.org/index.php?topic=373.0
It changed the url upon the move.
Seems some of the software functions will not recognize DMWW.
