To get a Google map working on your website, you have to get an API key. Unless you get it, you cannot show Google Map on your Website. The older version can only display a box with "Oops! Something went wrong. This page didn't load Google Map" message.
To fix the problem, just follow a few easy steps to get it working.

1. Just create a new API Key. However, you need to have a Google account before you can create and active it.
2. After login into Google account, you will see Get A Key tab on the top right of the screen. Just click on that and follow a few steps to generate a unique.
3. After generating the key, active it.
4. When the activation is done, put the key in the Google Map API Key field inside the SP Page Builder Configuration page.
