I tried again, and it gave me the error message again. I clicked the back button, and it showed icanhascheezburger.com in the address bar, but was taking a while. So, I clicked refresh. It brought the page up.
Since they are a VIP site on here, I figure it has something to do with that completely insane blank page + redirect thing WordPress does. I wanted to point it out so it can be looked into.
