Hi,
in one of my sites the API Key doesn’t work. I wrote it like your tuorial (http://kriesi.at/documentation/enfold/how-to-register-a-google-maps-api-key/) and i tried it with “www” and without. (Enfold Version 4.0.2) WP 4.7.3
And another Site does not need any API Key to show the map. In this version is no option to include an API Key, and google maps works (Enfold Version 3.4.7) WP 4.7.3
Maybe you have any idea – thank you for helping!
