Podcast error and can't refresh: Error parsing feed: Invalid XML: Error on line 190: Attribute name "disabled" associated with an element type "button" must be followed by the ' = ' character.

On examining that feed URL I get the message

'This RSS feed has been redirected, and SoundCloud cannot guarantee the safety of external links. If you would like to continue, you can navigate to 'https://itunes.apple.com/us/podcast/off-floor-exploring-learning-lessons-to-help -you-level/id1365875432'. RSS Readers and Podcasting apps will be redirected automatically.'

This is redirecting to the Store page, and trying to subscribe there produces an empty feed whose URL can't be checked. You need to go to SoundCloud and turn off the redirect - I can't advise on how to do that.

SoundCloud feeds are notorious for being broken by emoji. If you've entered any emoji into your show notes, remove them now.

The feed is non-functional because of the error; please always post the URL of the feed when you have a question - as the feed isn't working it's not possible to deduce it from iTunes. Emojis will wreck any feed, but looking at the error message it may be something else.

Your feed is in the Store and can be subscribed to in iTunes.
