Hi Ernest,
The url https://dev-www.motor.com is actually a dev environment and thus cannot be accessible by internet.
I checked the console for any javascript conflict, I could not find any fatal javascript error. However I did found a javascript error for one of the file related to another plugin called Optinmonster (see attached screenshot)
Can you suggest something to check if the plugin works fine in any given page?
Thanks
