If you see a message about anything to do with API restrictions that is google. I believe we had answered a few similar questions last year in the forums about this and the developer wrote a few articles such as this one.

Uncaught ReferenceError: GambitSmoothScroll is not defined
at (index):4
And that is under your locations index. I would clean up that error if you can since you have a lot of customization going on.
You might also want to use WP debugger to see if any errors are coming from your theme , another plugin or SLP. We do not see any errors related to WPSLP

The Do you want this site to allow access has to do with security measures with most browsers now as part of their privacy policies.
