Why can't I post on /x/? Every time I try I get a 'not logged in' error, but I'm clearly logged in.

I only use /x/ because I like looking at the paranormal/creepy stuff, and I never post in other boards, so I'm not sure why this is happening.<br><br>I'm logged in, I can see my name in the top right corner of the screen, and my email address can be seen in my browser when I log in.<br><br>So I try to see my account settings, and it says I don't have an account. Lol, what? So I try to make a new account, but it says I already have an account.<br><br>I'm in an endless, stupid loop and I don't know what to do, I've tried using a different email address and nothing seems to work.<br><br>Has anyone had this problem before, and did you manage to fix it?
