[SOLVED] RSS subscribe failing

Hello all.

I'm having issues with the RSS Subscribe button on my page coming up with errors.

This is what I get when I click on it:

XML Parsing Error: XML or text declaration not at start of entity
Location: http://kelfae.com/blog/feed/
Line Number 6, Column 1:<?xml version="1.0" encoding="UTF-8"?>
^


Please forgive my newbie-ness!
Help much appreciated, thanks.
