Check my index_body template

Did you have it modified at all? If not, you can simply restore the default template.

If you modified it and you ended up removing some parts of that template, I am afraid only you would know what is missing as others wouldn't have the knowledge of what you added to it. Unless, they modified it themselves.

The whole code you posted is from the original template

It ends with something you added (or at least something not present on mine):

Code:

<div id ="fa_stats">

This is from the original template that is gone:

So if you have nothing saved everything you changed is gone now. Maybe it is saved in a forum back-up?
