More than (just) Themes

As of June 22, 2016, Google has changed their policy regarding the standard plan of Google Maps API as they announced in their blog post. Keyless access to the API is no longer supported.

With the above said, the older implementation of Google Maps in our themes may become unavailable.
Our current implementation of Google Maps has been enriched with a Google Maps API Key setting.

To find it, please, go to the Appearance settings of your theme and find Google Maps API Key  under the the MTT THEME SETTINGS tab:
To generate your own API Key for Google Maps, please, follow the steps described in Google's official documentation at https://developers.google.com/maps/documentation/javascript/get-api-key.

After setting your own Google Maps API Key and saving the changes, please, do not forget to clear your Drupal cache.

If the aforementioned setting is not available for your theme installation, please follow the corresponding guide below depending on the Drupal version that you are using.
