Slideshow Javascript Issue

I have seen other threads about this issue but have been unable to resolve it using the assorted methods proposed. I was using a plug-in to generate slideshows but I decided to switch over to the Jetpack supported option. Unfortunately, my slideshows now fail to load and I get the following message: “This slideshow requires JavaScript.”

For an example see this post:

Any help would be appreciated. Thank you.
