There's suddenly a grey overlay on every page of my website including the backend. It will let me sign to the back end but I can't click on any links. Every time I try to navigate away from one of these pages it asks me if I'm sure. (as if I was working on an unsaved post or something)
Using chrome inspect element, I can see there is a div id called "overlay_div" that seems to be causing the problem but I can't find that CSS in ANY of my pages.
I've tried in both Firefox and Google Chrome. I'm on a Macbook Pro running Snow Leopard.
Checked every .php page and css page using the cpanel to try to find where that Overlay_div is being called from so I can remove it but I can't find it anywhere!

Any information would be incredibly appreciated. This non-profit is just days away from their biggest event of the year and having it's website down is really, really bad news!
