It happens to me. http://www.finanzaoperativa.com. However I have no WordPress SEO by Yoast. I just added a few days ago a plug in for related posts. However I suspect the true problem is my updating to WordPress 3.5. The error my feed shows is
XML Parsing Error: XML or text declaration not at start of entity
Location: http://www.finanzaoperativa.com/feed/
Line Number 3, Column 1:<?xml version=”1.0″ encoding=”UTF-8″?>
^
I installed Fix RSS Feed but no way.
I searched for blank lines but no way.
If you go to my feed and save the page in a xml format, the two blank lines at the beginning of the page are visible.
I don’t know what to do really.
Thanks for any answer.
