Hi,
“Google Maps API key” is required in order to show map and geo-location. You can add your Google Maps API key under General tab –> map settings of our plugin.
You can get your key under https://console.developers.google.com/flows/enableapi?apiid=maps_backend,geocoding_backend,directions_backend,distance_matrix_backend,elevation_backend&keyType=CLIENT_SIDE&reusekey=true&pli=1
Kindly make sure that the API key you have created has permission to work in the domain name you use now.
And you need to enable the Geocoding API in Developer Console:
The path to enable the API:
Go to Developer Console -> APIs & auth -> APIs->Search for Geocoding and click on Google Maps Geocoding API -> Enable API. And also verify your project has an active billing account: https://g.co/dev/maps-no-account For more information on usage limits and the Google Maps JavaScript API services please see: https://developers.google.com/maps/documentation/javascript/usage.
Thanks
