Invalid RSS Feed

Hello,

I am using Joomla 4 with Sermon Speaker 6. My RSS feed (from the Sermon Cast module) shows as:
cfec.org.uk/site/index.php/resources/aud...ormat=raw&type=audio

I would like to use it with Feedburner. I tried entering it into Feedburner, but it says "invalid source feed"
I tried with Spotify as well, but they also say it is invalid.

Could you let me know how to get a valid RSS feed for SermonCast?

Thank you.

I see where the issue comes from. I need to fix that in the code.
I'll try to do that this weekend.

While trying to fix the issue, I see that I already fixed that with version 6.0.6. And while checking back on your site, I see that your feed now validates fine.

I guess you had an older version installed and updated it now?

Correct. I updated and it works fine now. Thank you.
