Google map error "Oops! Something went wrong. This page didn't load Google Maps correctly.."
Google maps has changed the standard plan policy on June 22, 2016 requiring the API key to make the map work: https://googlegeodevelopers.blogspot.com.au/2016/06/building-for-scale-updates-to-google.html This feature has been integrated into each theme update. So the steps below will help you to get rid of the error and make the map work on your website:
1. Make sure you use the most recent theme version. Check the 'Change log' section on the theme description page to find out about the last version release.
4. Navigate to Theme Options - Service section in your admin, add the key into the Google Map API key field and click 'Save Options'. With that done, if the API key is generated properly, you will see the map working on the site.
