Hello Chris!

It is possible if your site hasn't the connection with Google Map API. You may check it via Studio->Dashboard->Host Tools->Server audit, the value of parameter "allow_url_fopen" (should be green "on"). Also please specify - is your Google Map Api key is active and you pasted it properly to Studio->Settings->General area?
