Comment:

 I just ran into this. In your theme's functions.php file, if you have an
 empty line OUTSIDE of PHP tags, it screws up BOTH the RSS feeds and the
 XMLRPC XML, which causes errors in feed readers and XMLRPC tools (like
 WordPress BlackBerry & iPhone apps).

 In your active theme's functions.php add:


 {{{
 code
 ?>

 <?php
 more code
 }}}

 That BLANK LINE is the important bit. After putting this in your active
 theme's functions.php file, going to http://site.com/feed or
 http://site.com/xmlrpc?rdp you'll get the blank line at the top of the XML
 files, making them invalid.
