Model Login not working

Hi, I just installed SCLogin module and installed it per instructions (set model mode and enabled JQuery via the "Load JQuery" option on the "Advanced" tab). The site is sapfmdev.cloudaccess.host

I can't get it to respond to a mouse click. There is a slight color change on hover but no action on clicking. Once logged in, I can get to the menu options and successfully logout. 

I inspected the source and noticed that there is an error reported (see attached screenshot) regarding "Uncaught TypeError: Cannot read properties of undefined...)". That error goes away if I unpublish the SCLogin module.

My configuration is very much like that described in another recent post (www.sourcecoast.com/forums/sclogin-enhan...utton-is-not-working).
    - Joomla 3.10.3
    - JoomShaper Helix Ultimate 2.0.5

Any help would be most appreciated.
