Why Google maps are not working anymore ?
Google Maps API now requires API key , otherwise maps wont load.
You can get api key from here https://developers.google.com/maps/documentation/javascript/get-api-key
Once you have the key update google map script, which is in at the very end of document :
<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY_HERE" type="text/javascript"></script>
