My site quit displaying my embedded media player. After a lot of digging, my expert found that it was filters on the Helix Ultimate template. He write me this, and I thought you'd be interested:
"Nothing is hacked. The audio player has nothing to do with the JCE
exploit or SP Page Builder, so you can park that worry.
The cause is a bug in your Helix Ultimate template, version 2.2.9. It
runs the "audio" field holding your Buzzsprout embed through a
security filter, and that filter is configured backwards. Its own
documentation says it uses an allowlist of safe tags, but the code
tells it to do the opposite, so it strips out the script tag the
Buzzsprout player needs to load. The empty container still got written
to the page, and the template wrapped it in a 16:9 video-shaped box,
which is the large blank space you were seeing above each episode.
I've fixed it with a template override, so the embed renders as you
entered it again. Episode 415 is playing properly now and I checked
five other recent episodes too. The fix sits in the template's
overrides folder rather than in the template or plugin files
themselves, so a future Helix Ultimate update won't wipe it out.
The same faulty filter also strips iframes, so a video embed from a
source the template doesn't recognise would disappear the same way.
Worth reporting to JoomShaper so they fix it at source."
I hope this helps squash a bug.
