Ultimate Fade-in Slideshow has stopped working

1) Script Title: Ultimate Fade-in slideshow (v2.6.1)

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...nslideshow.htm

3) Describe problem:

I have had the Fade-in Slideshow working on this site for a long time - https://joydimenna.com/ (currently another slideshow is on there as I couldn't get the fade-in one to work any longer).

I was swapping out form code in an iframe - easy enough - uploaded the page and the fade-in slideshow quit working. Not sure if it has a part in this.

On this page - https://joydimenna.com/indexnojuly2019.html I have removed the iframe form code completely. Re-worked the Fade-in code. Saved a new version of the js and uploaded it. Still does not work .. EXCEPT when I go to Internet Explorer where it works! Why is it working on IE and not Chrome, Edge or Safari?

Please help! I'm going a bit crazy with this one.

Thank you!
