I don't get a valid rss. Any suggestions ?
Looks like it starts with an empty line.
Maybe you just follow the discussion about exactly the same point here: http://vanillaforums.org/discussion/28448/rss-feed-not-working-please-help-tried-everything-i-think-i-see-why-but-what-file-to-edit#latest

Thanks. Fixed it. I had an unreadable boostrap.before.php in /conf (that solved the white line) and I've noticed that putting adsense-code in a Pocket (plugin) in Page = All, Content, Before breaks rss as well.
