wow, very strange problem out of the blue

[Chadi]

This is very very odd, strange. My site www.talkjesus.com all of a sudden has this padding (horizontal / vertical) around the main body, any page. For example, notice the logo? The purplish background is the padding area that should not be there. The white should go all the way to the sides and the logo/header should be up to corners, no padding or margin or spacing of any kind.

Even worst, IE8 is missing the header background color.

I confirmed this is an actual problem, not just me (cleared cached). Confirmed even via browsershots.org / http://browsershots.org/http://www.talkjesus.com/

Here's the freaky part:

- absolutely no style changes were made at all
- absolutely no new plugins were installed, removed, modified at all.

Nothing was modified in any shape or way at all in the forums admincp or any external css outside the admin panel. Plus, I am the only admin with access to the backend and server. Nothing has been modified in weeks.

I confirmed this in IE, Firefox and Chrome.

Can anyone solve this mystery? I'm baffled.
