Henrik on "Google Maps"

Hello,
we need some help with Google Maps. Our new website has been ruing just for a day and we are still having a problem with Google MAps loading.

Advice anyone please?
Thank you.

Is that part of your theme or plugin?

THanks a lot for a reply by retu.
Well, our website is based on this template:

Seems Google Maps is part of our theme.

For me it looks like you need an APIKEY to your Google maps.
