My Pages all of a sudden are not working

Hey Folks,

I had my page up and running recently, everything was working properly. I then made some changes to the Header and someone else wrote some drafts and now the pages aren’t working and I’m getting an error 404.

Even when I login to manage the pages and click the “view this page” link it comes up with the same error. Anyone have any ideas?
