Hi,
Open the console log of your browser on that page and you'll see this error message:
js?key=AIzaSyASMDojvUxUwH_nT-R0guY-OqzuhCTl15k&libraries=places&callback=initAutocomplete:82 You have exceeded your daily request quota for this API. If you did not set a custom daily request quota, verify your project has an active billing account:
g.co/dev/maps-no-account
For more information on usage limits and the Google Maps JavaScript API services please see:
developers.google.com/maps/documentation/javascript/usage
_.te @ js?key=AIzaSyASMDojvUxUwH_nT-R0guY-OqzuhCTl15k&libraries=places&callback=initAutocomplete:82
So as it says, there is a problem with the setup of your billing account at Google Maps. That's why it's not working properly.
