Hi Casper!
I’m sorry you are having this issue. 🙁
I can see there are some JavaScript errors when inspecting that page. I can also see that our plugins scripts are being minified somehow. Our plugins are already minified so you won’t need to minify them > https://theeventscalendar.com/knowledgebase/problems-with-minification/
I recommend you try disabling any type of minification and see if it changes anything. If it doesn’t, then we will need you to go through our Testing for Conflicts guide and let us know what you can find in the process.
Also, we were not able to import your system information. Please go to Events –> Settings –> Help in your WordPress dashboard and copy your system information in a private reply.
Let us know how that goes.
Best!
Victor
