Error in map/placemeark editor: Oops! Something went wrong.

Using Joomla 3 with latest version of ZHGoogleMaps. This has been working for many years, not a newer install. The map will not appear in the backend editor. Maps appear OK on the front end.

I first tried upgrading to the latest version of ZHGoogleMaps. I have tried with OSM in editor set to No. I have tried with Google set to No and OSM set to Yes. It was set to booth Yes when it was working before.  I have tried creating a new API key. I have tried changing API restrictions to allow only Google maps APIs. See error below attached. Any ideas where to look for resolution?

Hi
Check browser console for errors

In the console this is the only error I see that may be related:

Google Maps JavaScript API warning: NoApiKeys developers.google.com/maps/documentation...messages#no-api-keys util.js:58:65

I did try creating a new API key.

Open component options and check did you enter your correct API key there

Yes, I checked it and i twas the same as the value in Google, and has been for 5 years. I tried creating a new key and it behaves the same way with the new key. It always works on the front end. It's just the backend editor where it fails.
