I’m also experiencing this problem. I tried both the wp-rss.php and wp-config.php solutions offered. There is NOTHING in these files that is pulling in the google analytics code from my header, but when I attempt to configure a FeedBurner feed, i get the same message about “junk” in the feed.
At first, I had just inserted the Google Analytics script into my footer.php file through the “edit theme” page. When I began experiencing this problem, I decided to delete all analytics scripts and install the Google Analyticator plugin. Even with that plugin deactivated, I get the exact same error message.
I should note that I am running the WordBook plugin that feeds my posts to my facebook. I’ve also enabled the facebook “notes” application to import new posts. So some kind of feed must be working…? I don’t understand.
I need help ??
