Hi,
I have the same problem: wfw:commentRSS should be wfw:commentRss.
I’ve used the latest validator with same problem. I’ve changed RSS to Rss in wp-rss2.php per recommendation and same feed warning persists.
Validator warning link: http://validator.w3.org/feed/check.cgi?url=http%3A%2F%2Fprimelinetrading.net%2Fblog%2F%3Ffeed%3Drss2
Blog is not updating so I checked Feedburner site which suggested validating feed. Any help appreciated.
