Google Maps not Showing in Contact page

I am using the MBuilding theme and the google map is not showing on the contact page. I have everything set correctly. Please help.

Hi!

According to the Google Maps APIs Standard Plan updates implemented on June 22, 2016 all Google Maps JavaScript API applications require authentication.
To get started using the Google Maps you have to generate an API key for your website and enter it on the Integration page of the theme settings ( this option is supported starting with 2.4.3 version of the themes ). If your theme version is less than 2.4.3 you have to update the theme as well.

Use the instruction on how to generate an API key here: https://developers.google.com/maps/documentation/javascript/get-api-key
