JQMIGRATE error

Thanks, I'll take a look. I am more within the SysAdmin realm of experience as user rather than developer. Most of my development was in *NIX shell scripts, SGML and HTML over the last 40 years. I am retired and have been for over a decade, but I stay active in TM and other non-profit activities including FBI InfraGard -- as a volunteer.
I, too, am intrigued with the problem. I will followup as I learn.

I accessed your site from Windows 10 Chrome, Edge, Firefox and see no errors.

Did you have the developer tools enabled?

Thanks, Brian, for the idea. No Developer Tools or Insder Settings. That was worth checking though.
I think it is popup related since I just discovered that Pathways popups fail.
Popups not blocked for the usual sites: [*.]csod.com [*.]toastmasters.org [*.]toastmasters,org
I will delete and recreate those allowed sites in case there is a freaky, hidden character embedded.
My investigation continues.
