Error in iTunes feed

iTunes (ie. iTunes connect) flags an error in my podcast feed https://www.geemco.de/artikel/feed/itunes/

Error parsing feed: Invalid XML: Error on line 7: Attribute “content” bound to namespace “http://www.w3.org/2000/xmlns/” was already specified for element “rss”.

I’m not aware of having changed something. The episodes listed look fine (in the serveral apps as well as on iTunes website/previews).

Any idea about that?

I cannot see an issue in your feed. xmlns:content="http://purl.org/rss/1.0/modules/content/" is defined exactly once.

Me neither. And so iTunes, just checking. Strange. Don’t know what happened here.

But thanks for getting back anyway.
