[Plugin: Satellite Slideshow] Why is my live site different?

Hello everyone. I’m having a heck of a time troubleshooting a discrepancy between my development version and my client’s existing live site.

Development version:
https://dev.almamidwifery.com/home-birth/

Live version:
https://almamidwifery.com/home-birth/

As you can see the Satellite Slideshow is broken on the live site, but not the dev site. The dev site is a mirror created by the Duplicator plugin (that’s what replaced all the quotes with gibberish, but otherwise the two sites seem the same to me). Where would I look to troubleshoot the differences and get the live site working?
