Google Maps Geocoding
Since July 2018, Google Maps Geocoding is no longer a free service. That's why using the location address in it's text form (i.e. "Paris, France") won't work in our theme by default anymore.
There are two ways around it:
1. Insert the location in the "lat,lng" format. To obtain those coordinates, you may use a simple service like:
https://www.latlong.net/convert-address-to-lat-long.html
For "Paris, France" it would be: 48.856613,2.352222
2. Enable the Geocoding API in the same project that you have the API key (used in Theme Options) in:
