RSS feed can’t be fetched

Hi!

On March 16th, I got an email from Pinterest saying, “Your RSS feed can not be fetched. Please make sure that the feed URL can be opened.” I didn’t get a chance to check it out, and then on April 5th, 6th, and 7th I got additional emails saying the same, so I finally took a peek last night.

According to the W3C feed validator –

“This feed is valid, but interoperability with the widest range of feed readers could be improved by implementing the following recommendations.

line 33, column 0: Use of unknown namespace: com-wordpress:feed-additions:1 (11 occurrences) [help]

<site xmlns=”com-wordpress:feed-additions:1″>57684931</site> <item>”

I disabled all my plugins (15) and turned them back on one by one, and ran the validator each time. Jetpack is the only plugin that caused the error – when it’s disabled and the other 14 are running, I get this result from the validator –

“Congratulations! This is a valid RSS feed.”

Any help getting this resolved would be appreciated.

Thank you!
