Your error message is more different.  I think it can be with a posting after a time out.  You can solved this in most situations with going as the user in the "my settings"  adding subscribtion to all forums save and restart the application (in Host Settings).  Then try to post with this user account, if it work now unsubscribt the forum notification in "My Settings".
