rss feed error "XML or text declaration not at start of entity Location"

[eluser]Unknown[/eluser]
I still don't get it sorry I am noob on PHP I just recently started a blog using self hosted Word Press and the feed works on IE but not on FireFox giving me the error:

XML Parsing Error: XML or text declaration not at start of entity
Location: http://www.farneville.com/feed/rss

Line Number 2, Column 1:<?xml version="1.0" encoding="UTF-8"?><!-- generator="WordPress/2.9.2" -->

Now given the solutions here I do not know where to find the php file that has white space.

Lols while writing this I just found the solution it might be worth noting for other people looking for the same. Here it is http://validator.w3.org/feed/docs/error/...kLine.html :lol:
