   After I upgraded to v2.3, my RSS feed can't be accessed anymore. When access to RSS feed, the browser display:

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

   Somewhere, some plugin or other file has a blank line at the start of it. Could be wp-config.php, could be your theme's functions.php file, could be any plugin. No way to tell.

   Find it, and remove that blank line.

   Hi Otto, you are really brilliant, I tried to deactivated all plug-ins then enabled it one by one, and the feed worked again like a charm. Thank you so much !
