Error: Google Maps API warning: NoApiKeys

If you see a warning in your browser's Javascript console that says Google Maps JavaScript API warning: NoApiKeys https://developers.google.com/maps/documentation/javascript/error-messages#no-api-keys the reason is that you haven't configured your Google Maps API keys or there's a conflict with another plugin/theme trying to load the Google Maps script at the same time.

There are two ways to fix this problem:

1) Add your Google Maps API key in the GravityKit's Settings screen

2) Add your Google Maps API key on the settings page of other plugins or your currently active theme
