This article effects the WordPress StoreLocatorPlus users “Do it yourself “
MAP Service and API Keys
Changes as of June 11, 2018 will effect the WordPress Store Locator Plus (DIY) community. Google requires all sites using map services to have an API key with a billing account attached. See Google Developers console.
The Browser key is used to display the map and handle user-input addresses during a location search. The Geocoding key is used on your WordPress server to geocode locations you’ve entered via the Google API. You do not need the geocoding key unless you have added referrer restrictions.
