Google Map API Warning (NoApiKeys)

If you want to use Google Maps, you should get API key.

In template HTML files you should find google maps api js file. Example:

<script src="https://maps.googleapis.com/maps/api/js"></script>;

And add to this address your API key. Example:

<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY"></script>
