I host the podcast files at my own webspace, so there’s no other feedburner plugin or something else.
I installed two feed related plugins: RSS Image feed and Smart Youtube PRO. I deactivated both – no success. I deactivated WP Rocket also – no success either.
If we can’t find a solution this way, maybe there’s a chance of a shady hardcode? I submitted the “feed/podcast/”-feed to iTunes. The only fix I need is about the links for Android/Rss in the subscribe widget and under the podcast files in an article. Can I hardcode them? Where? Thats not pretty or substantial, but at least I would have gotten what I need.
