Whenever I have the W3TC plugin enabled, my RSS feed breaks with this error:
XML Parsing Error: XML or text declaration not at start of entity
Line Number 2, Column 1:<?xml version="1.0" encoding="UTF-8"?>
As soon as I disable the plugin, the feed goes back to normal. Is this a bug with W3TC? Why is it adding a blank line to the top of my RSS XML feed?
Also, I have tried enabling one type of caching at a time - as soon as I enable any one type of caching, my RSS feed breaks again.
Ideas? Is there an official bug reporting site for W3TC?
