I'm trying to enable the google map like on live demo exemple but I found few documention about it.
I still got the black&white map.
$config['geocoding']['enable'] = true;
$config['geocoding']['api'] = 'google';
$config['geocoding']['default']['lat'] = "37.7463058";
$config['geocoding']['default']['lon'] = "-25.6668573";
$config['frontpage']['map']['region'] = "world";
$config['frontpage']['map']['resolution'] = "countries";
$config['frontpage']['map']['dotsize'] = 5;
$config['frontpage']['map']['realworld'] = false;
