PHP Not Working

[Cain]

Hey I am new ;)

Anyway I seem to be having a problem with PHP files.

I get a 404 error on them on any other browser and a broken page on
Chrome.
I found a small log and here is the details from it

2011/04/16 15:51:27 [error] 22810#0: *1 upstream sent unsupported
FastCGI protocol version: 60 while reading response header from
upstream, client: 81.99.173.32, server: thefoool.co.uk, request: "GET
/cain.php HTTP/1.1", upstream: "fastcgi://81.99.173.32:80", host:
"thefoool.co.uk"

Can you please tell me what's wrong with it? :)
