Calendar-app details not in popup

[isd-17]

On this site:

Calendar - Apps - App Store - Nextcloud

you can see the details of an event in the calendar openin in an popup.

On my site under:
https://isdcomputer3.sp-kunde.de/kalendertest_di.php

there is only a small sidebar on the left, but no popup.
How can I change this?

The Basics

• Nextcloud Server version (31.0.6):
• Web server and version (Apache 2.4):
• PHP version (8.3):

Thanks for your report

I agree the view when opening an event is a bit small.

What can I do to change this?
Must be possible to do by css, but I can’t do it…
