[SOLVED] Oh no! I've lost my foot!

I'm putting this here instead of the footer area so more people will see it. I have a feeling this could affect other people who try to modify the theme's files instead of just using the theme options.

I just looked at the bottom of my front page, and the footer is gone! The source code shows this as the last bit on the page:
That's it. Nothing after the center tag, yet the page displays fine except for the copyright and powered-by text.

I must have somehow ruined this while modifying index.php or bfa_header, at some point. I can't easily find out what I did. Flynn, does the missing part give you a clue as to where I should look? I suppose I could just overwrite the modified files with the clean originials, but I would really like to know what I did wrong.
