I'm trying to create a new thread in Math & Science Learning Materials, but this message comes up when I click "New Topic": a7d07c8114, you do not have permission to access this page. This could be due to one of several reasons: Your user account may not have sufficient privileges to access this page. Are you trying to edit someone else's post, access administrative features or some other privileged system? If you are trying to post, the administrator may have disabled your account, or it may be awaiting activation. I've made sure I'd activated my account, and I'm not trying to do any of those things. It doesn't seem as if an admin has disabled my account (I was never notified of it, plus it seems I can post just fine here). Would someone please tell me why this is happening?
