Good evening Jan and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear that the map view did not work properly on your install.
I would love to help you with this topic.
I just went ahead and checked your website and everything seems to be working properly.
Can you confirm ?
If that’s not the case, as a first troubleshooting step, could you please provide us with your complete system information in a private reply using the instructions found in the following link?
