It appears to be working fine for me. Were you able to get it resolved?
Even the W3C feed validator says its valid. Have you tried to reactivate one plugin at a time to see which one might have been the culprit?
Hmm, for whatever reason, it’s working now. I guess all that deactivating and reactivating did something eventually. Now my email is broken, who knows how I did that but hopefully I’ll be back up and running completely again soon. Thanks for your reply!
