Broke in wordpress 5.5

[normhayes]

WordPress 5.5 no longer supports legacy JQuery code. I fixed this with the jQuery Migrate Helper plug-in. I don't know JQuery that well, but If you know JQuery, it looks like can be fixed by updating the Java scripts.
Here is of list of things that looks like it needs to be changed for it to work in WordPress 5.5.
