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 API is used on your WordPress server to geocode locations you’ve entered via the Google “Places” box and APIs. You do not need the additional geocoding “key” unless you have added referrer restrictions. You do however, need to have the geocoding API enabled in your Google projects library.
