[SOLVED] Feeds not working

This is the error I get with Firefox. There never was a /feed directory created

XML Parsing Error: XML or text declaration not at start of entity
Location: http://sparks-mexico.com/feed/
Line Number 2, Column 1:<?xml version="1.0" encoding="UTF-8"?>

I see the Comments Feed is working from the folder /comments/feed (in Firefox)
But posts just wants the folder /feed

I have a Feedburner account but not sure it would work if these don't
