Error message appearing on main page

[DEATH eVADER]

Whenever I load up halflife2.net, I get a error message stating

Internet Explorer cannot open this internet site
http//www.halflife2.net

Now I can still get on to the frontpage, but during a certain condition:
-I have to be browsing the site's forum at the time, and would have to either create a new tab, or open up a new Internet Explorer window

Is anybody else getting the same problem?

Wish I saw this earlier... fixed now. Our lightbox image plugin was causing an error.

Yeah, had that with this site on a few others.
