Using Google Maps on your website now requires a developer API key.
The Google Maps script in WYSIWYG Web Builder has been updated so you can configure the key.

You can create it here:

Select 'Browser key'. Also make sure 'Google Maps JavaScript API' is enabled for your account.
Please carefluly read the Google documentation.

After you have created the key you will need to replace the YOUR_KEY value in the properties of the script.
Note that local preview may not work, this is unrelated to WYSIWYG Web Builder!

This requires WYSIWYG Web Builder 11.2 (build date July 19, 2016) or newer!
