The error you see occurs if you are using the Google Maps API on localhost or your domain and it was not active prior to June 22nd, 2016, it will require a key going forward. To fix this problem, please do the following steps: 1.) Create an API key: https://developers.google.com/maps/documentation/javascript/get-api-key#get-an-api-key2.) Populate the key in the optional api key section of script below. 3.) <script src="//maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&key=YOUR_API_KEY" async="" defer="defer" type="text/javascript"></script>4.) Place this in above map code on deployed page.(where you wirte ---- <div id="map"></div>)
