MP3 Media not working

I moved my site from .com to .org a few weeks ago. Most things look fine, except for my music page. The page should have a player to listen to several audio files. (I don’t want it to offer download capability). For example, the first song is uploaded to https://www.thatjonathanriggs.com/wp-content/uploads/2010/09/be-glorified-male-solo.mp3, but the player does not appear on the page. I have verified that the file is at that URL.

The page in question is https://www.thatjonathanriggs.com/singing. Is should look like https://www.jonathanriggs.wordpress.com/singing.

Please help.

Thanks,
Jonathan
