My audio tracks don't play but I can see the sticky footer player. What's wrong?
The issue seems mostly related if you use a CDN (Content Delivery Network) or GoDaddy Shared Hosting (GoDaddy enable a CDN by default)
The player shows up at bottom but it won't play any audio. This happens because you have CDN (Content Delivery Networks) enabled in your GoDaddy control panel. If you check your console log (with Chrome), you will see a CORS Policy error such as this one: https://d.pr/i/Be7qSM
There are 3 different options to resolve this issue:
1) You disable your CDN on GoDaddy (check in your Godaddy panel)
3) You check with your CDN to add yourdomain.com to its CORS header.
