Map no longer working after upgrade to 4.13.0

Hi Guys,

I just upgraded on a development site to test the upgrade and the maps are no longer working on the front end. The backend is fine

On the front end I see first a grey box and when I switch between the pictures and the map it eventually shows just blue water. I then zoom out like 10 times to see some tiny islands. It feels like it just sits in the middle of the map. Screenshot after zooming out 10 times.

Please could you assist.

Thanking you in advance.

Kind regards,

Regine
