The placement of maps on new websites requires an API key. This key can be entered via 

Within Google's API Manager, you will need to

  • Create a new 'Project', if you haven't created one already
  • Within the Overview, find the Google Maps JavaScript API, and the Google Maps Geocoding API and enable them both.
  • Within the Credentials, create a new 'API Key', of the type 'Browser Key'
Copy the key generated and enter it in the Map Locations->Settings dashboard page.
