Google does not show zhgooglemap, but zhgooglemap-lightbox ok

Sorry, over the weekend I tried the placemark migration utility GoogleMap to OpenStreetMap to base that map on OpenStreetMap. Worked great! But no chance to manually migrate rest of ca 500 maps to OSM...
familie-abderhalden.ch/index.php/reisen/...ingplaetze-googlemap   error!
familie-abderhalden.ch/index.php/reisen/...e-campingplaetze-osm

So still a problem:

• all my GoogleMaps called via {zhgooglemap:n;Zoom;;300;200} show error
• GoogleMap called via Menu shows error
• all my GoogleMaps called via {zhgooglemap-lightbox:n;"large map";900;750} display correct

Coexistence problem with other Joomla extensions?

First link - I can see error in console
"Google Maps JavaScript API error: ExpiredKeyMapError"

Check do you enable Google Maps JS API in key configuration (if it is not expired), or create new one if it is expired
