For the past week or so whenever I login to the forums after logging in I'm directed to a page stating;

vBulletin Message

Invalid Redirect URL (http://epforums.org/)
I'm able to navigate to the actual forums fine after seeing this, it's just strange. Mostly just curious if any of the administrators might happen to have any insight into why it does it/if it's a known issue.

If it's relevant I get the error on both Chrome and Firefox (both updated to the latest versions).
