Since the URL file access is disabled on the most servers you need to edit functions.php file.
find this:
$api_url = "https://maps.googleapis.com/maps/api/geocode/json?".$type."=".$query."&sensor=false&language=".$options['language'];
add below:
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $api_url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
$json_answ = curl_exec($ch);
curl_close($ch);
remove this:
$json_answ = file_get_contents($api_url);
And it’ll work fine!
hope the developer fix this in the further version.
