BROWSER: Firefox 3.6.8 I was reading that topic "Probably not a good idea..." and tried to click the image posted by the OP. I was taken to the login page (note: I was already logged in) and received this error: XenForo Community - Error You must be logged-in to do that. So, I re-entered my login info and clicked 'Login'. Then, I was presented with this error: XenForo Community - Error Security error occurred. Please press back, refresh the page, and try again. Confirmed in the topic in question by Lawrence.
