As you may know, Google Maps just recently made changes related to the use of Google Maps. Effective June 22nd, Google will no longer support keyless access (so that is any request that does not include an API key).
For full details see here
Action Required
If your theme includes a map module or page builder element, then there will need to be an option for the user to be able to add their API key in the theme options. So that any Map element which uses Google Maps will be using the users API key.
Users can request an API key here
If the theme is using Visual Composer for a Google Map element, then no changes will need to be made, since Visual Composer uses an emded code.
