Why Google Maps doesn't work?
Sometimes, you might have an issue with Google Maps saying the following
This happend when your domain is new and has never used Google Maps prior June 22nd, 2016.
Google Maps recently changed its TOS and requires now an API key. So pH7CMS 2.0 and newer allows you to add a Gogole API key.
To do it, go to your admin panel -> Settings -> General -> API -> Google Maps API Key
We cannot do anything for that, you will just have to move your site to a domain that respects the TOS of Google Map's service
