As you can see I get an error:
XML Parsing Error: XML or text declaration not at start of entity
Line Number 3, Column 1:<?xml version="1.0" encoding="UTF-8"?>
I've been looking in the wordpress forum and found the fix-rss-feed plugin, which deletes blank lines. But no results.
Through feedburner I can ping to my feed, which works.
The feed validator of feedburner showed me this:
line 1, column 1: Blank line before XML declaration
I've been digging into the code of wp-rss2.php, wp-atom.php, functions.php but can't find any blank line...
Someone has other idea's? Would be most welcome.
