Live HLS

Hi,

I have a live HLS stream which will not play in the flowplayer WordPress plugin. The grey squares rotate forever. To narrow down the cause I created a completely empty wordpress test site:

https://www.pjdaniel.org.uk/wp/flowplayer/

I have tried a demo stream
https://wms.shared.streamshow.it/carinatv/carinatv/playlist.m3u8

and my own stream
https://livestream.stpaulsealing.com/live/stpauls/index.m3u8

The HLS and Live options are ticked in the plugin settings.

Any help would be great,
Peter.
