Problem
When using the search bar to search for a zip code or an address, the search hangs, the spinning ball just keeps going.
Solution
If you open up the JavaScript console of the browser (press Ctl+Shift+J in Chrome or Ctl+Shift+K in Firefox), there will be an error like this:
Geocoding Service: This API project is not authorized to use this API. For more information on authentication and Google Maps JavaScript API services please see: https://developers.google.com/maps/documentation/javascript/get-api-key
This error means that you need to enable Geocoding API for your Google maps key which makes possible finding locations by their address string. To enable it, please do the following in your Google Cloud control panel:
Click the Library link in the left menu.
In the Search for APIs & Services field start typing in geocoding, the Geocoding API will appear.
Click it, then click Enable there.
