Forum:Login problem

My username is actually 31dot, and I am an admin at Memory Alpha and the Law & Order wikis. Whenever I attempt to log in to a wiki other than Memory Alpha, my log in in rejected and I get the following message: "There seems to be a problem with your login session; this action has been canceled as a precaution against session hijacking. Go back to the previous page, reload that page and then try again."

When I do so, nothing changes. I can log into Memory Alpha fine, just nowhere else. I've already sent a message through Special:Contact but I didn't know if anyone here could offer help. Thanks 72.224.177.228 11:10, February 22, 2012 (UTC)
 * That happened to me before, it will reload the page, then click on your user page icon on the top-right corner of the page, then it should work &mdash; [/wiki/User:Sam_Wang S a m ] [/wiki/Message_Wall:Sam_Wang W a n g ] 12:42, February 22, 2012 (UTC)
