Cdfreakstempdown?

i get a “cdfreakstempdown” prompt three times when i load ANY forum page, asking for my id/pass. any way to make a simple 404 / out of order page, instead of this?

every time I go to a new page in the forum I’m prompted for username and password for “CDFREAKSTEMPDOWN” at www.cdfreaks.com. If I close the prompt 3 times the page loads as usual. What is this CDFREAKSTEMPDOWN and why should I log into it?

We have just been updating some server software, and something just took a little more time then expected…
