I'm using the latest build of the forum, it was working perfect, but suddnly who ever enetrs the page with the forum module non of the modules is loaded i see only empty containers and this error message: Request is not available in this context

Note that the forum is configured that only registerd and subscriber users can post, further more they the forum container settings is that all the roles can view it but only the administrator, registered, and subscriber roles can edit it.

one last note, when i login as admin or host I dont face any problems and everything works fine, but when a registered user or subscriber logs in he gets the above behavior mentioned above. note that when you are not logged in, you can surf the forum normally.

Fast response is appretiated
