That's the encoded version. If you don't have the source, and you were supposed to get it, chalk it up to a lesson learned. Reputable developers don't give you an encoded file when they've sold you the source. Either you pay for the unencoded source and get it, or you pay for the encoded file and you have to pay the developer more money to modify it. If you have another version of the index file (index.txt or index.src or something), start with that, not the encoded version. (This sounds like you found a developer on a "cheap coder" site.) Gambimolocea has the right idea, but you won't be able to do it, even if you find a page that explains the method, if you can't at least write PHP code. And, if you could, you probably would have written your own site. If you haven't paid for it yet (you shouldn't until you see that it works), forget it and pay to have it done the right way this time.
