cannot save event created on front end

I know this issue has been discussed in various other posts but I have yet to find a solution to the problem as I am experiencing it.
I have created a menu item to allow front end event creation. After filling out the form completely, I hit the "Save" button and nothing happens.
The browser debug console shows "ReferenceError: WFEditor is not defined[Learn More] jevents-add-event:967:6 ".

I get the same result with the same message whether I use Firefox or Chrome. I am using JEvents v3.4.50 Stable and Joomla! 3.9.6. I am using Windows 10.

I have set "Fix any jQuery conflicts" to "YES".

I am using JQuery Easy plugin. It reports:
