I seem to be unable to make any new posts either in a thread or in PM. Also, I can't create a new thread as it gives me a 404 error. In the case of posting in a thread I get sent back to the first page of the thread I attempted to post in and nothing has changed. When I try to edit an old post I get sent back to the original post and none of the changes are made.

edit--

Also it appears I am unable to subscribe to any threads.

Well a good first question always seems to be, which browser are they using?

Chrome seems to be my problem at the moment although it's never had an issue before now. At least I can do things now...
