Google has switched to a pooled quota for the Google Maps API used without an API key.
As a result, you might see an error from Google like this:
Oops! Something went wrong.
This page can't load Google Maps correctly. For development purposes only.
If you've had an API key (license) established, the funding has likely been depleted or funding source has an issue. Check the funding source and balance with Google.
If you've been using Google Maps without an API key, MetaLocator has options for you and one is included with your MetaLocator subscription. Note this message from Google can occur at any time without notice if you've elected to use Google Maps and have not obtained an API key.
There are two options available:
Switch to Mapbox Maps: This option causes your interface to use a different mapping library. The behavior and functionality is identical except the map tile imagery comes from another provider.
Obtain a Google API Key: With this option you can continue to use the Google Maps API with your own individual map view quota.

Log in to your MetaLocator account, and choose Interfaces. Click the name of the Interface in question.
