Google Maps JavaScript error

Hello,

After i needed to change the domain in my WordPress install (from mydomain.com to mydomain.eu the Google Maps isn’t loading anymore and giving the following error:

“Oops! Something went wrong.
This page didn’t load Google Maps correctly. See the JavaScript console for technical details.”

I tried to delete the map and place it back again on the page but no result. Could you help me out on this problem?

Regards,
Patrick
