Google maps: "This page can’t load Google Maps correctly" error

This message is displayed when your API key has not been correctly set up, accompanied by a “For development purposes only” watermark on the map tiles. This will also be displayed if you have not set up billing for your API project.

When this message is displayed underneath an address field, this is because the Google Maps Places API has not been enabled for this project.

You must enable the following APIs for the plugin to be functional:

  • Google Maps JavaScript API
  • Google Maps Geocoding API
  • Google Maps Places API

Please refer to the documentation on creating a Google Maps API Key for full instructions.
