Theme stripped from index

I was using ozh’s who sees ads and decided to remove it. I deleted all of the functions that called for it but in the middle of the process the index stopped showing the theme and all designs.

Here is what it looks like now.

As you can see, its not a pretty site for our customers. What could cause this and how can I fix it?

I’ve already made sure there are no white spaces in between the ?> or whatever it is.
