Welcome, jrouse.

That error typically arises, because a browser extension is interfering with the page’s JavaScript. If you disable them, it could help.

Another cause is a caching error related to the way jQuery is used on the page. Hard-refreshing the page should help (clear browser cache).

Hope this helps

The hard-refresh worked. Thank you.
