After upgrading to Piwik 1.3 the FeedBurner widget shows “Feedburner stats didn’t return as expected.” no matter what feed name is inserted. It worked in 1.2.1.
Thanks for your suggestions.
Update: It seems the problem has magically been solved. FeedBurner statistics are correctly displayed again. Perhaps the FeedBurner API was down for some time.
