fatal error jwplayer7

In the backend opening a sermon returns this error:

jwplayer 7 most likely doesn't work with Joomla 4 and SermonSpeaker 6. That is because they don't offer a free player anymore and I can't develop it without paying for a license.

You will have to use the mediaelement player:
github.com/Bakual/SermonSpeaker/releases...ker_mediaelement.zip

The issue is solved.
This is also a nice player!
