Hey David Wallace,
It seem’s you haven’t set the google map’s API key.

How to set API key?
Admin -> Appearance -> Customize -> Realia General
Find Google Browser key option on bottom of the panel.
You can create a new API from there by clicking that link.
Refer the below Image.
If you still have issues, please email me your website url and login credentials (if you can). I will give a look.

Thanks,
Ponvendhan
