Thanks for the reply, I have spent the last two evenings at this problem and your suggestions were very helpful.
Ok so I have spun up another server and now the podcast player works for other podcasts… but sadly not mine.
To answer your questions.
1. No, I do not get any error message
2. The native RSS widget doesn’t work with my podcast either, it doesn’t show information from the podcast RSS instead, shows a single article.
3. Health check plugin showed that I was missing some PHP modules. I have sorted this issue but no luck. Also says my PHP version can be updated, but since I am already on version 7.0, so I haven’t addressed this yet.
Anyways thanks for the help, I think that I need to look into the RSS issue, maybe WordPress’s own RSS feeds are affecting my old RSS feed, cause it isn’t working on iTunes either.
