MediaElements.js Player works in webflow.io site, but not custom hosted URL

[switchboard]

Hi friends,

Here’s my share link:
https://preview.webflow.com/preview/fcchudson?preview=b3a7068dd2b25b2da029e2a184efb774

I’m trying to embed an HTML5 audio player, MediaElements.js into this client website.

I got it working in the “staging” site: http://fcchudson.webflow.io/sermons/the-gospel-atmosphere

However, in the custom URL, it defaults back to the browser-native audio player: https://www.fcchudson.com/sermons/the-gospel-atmosphere

You can find the header css and footer scripts in the “Sermons” Template.

Any ideas? Thanks!
