Hi guys,
1.- Create a new api key of google maps (https://developers.google.com/maps/documentation/javascript/get-api-key)
2.- Search this files (acf-google-map-extended-v4.php & acf-google-map-extended-v5.php) on plugins\advanced-custom-fields-google-map-extended\ and edit the lines 28 and 27 respectively
3.- Add “key=YOUR_API_KEY” followed by “//maps.googleapis.com/maps/api/js?”
Vibes.
PD: Sorry for my english.
