As the other users have clarified, no one is actually trying to get into your account. The forum can be a bit derpy, and although you may receive this message, your account should be safe. I would suggest refreshing the page, but if that doesn't work, you could try opening the page in a different internet browser. Since this has been pretty thoroughly explained, I'll go ahead and lock this. If you're confused about any error messages in the future, don't hesitate to ask, though. c:
