Map unavailable

Hello users,

We can’t get the map working at our website.

We have a working google map on the contact page, /contact/.

We have used the same maps api key for the wordpress theme, as the event manager plugin. Also the address is filled in right, you can see that on https://prnt.sc/mjyo3l

We don’t get any errors in the console, so we are really frustrated to get it working but don’t know how. Can anybody help us?
