The issue you are facing:
I have calendars that I am sharing with a group. Every time I click on one of these calendars in the left hand menu, I get the message ‘An error occurred, unable to change visibility of the calendar’.

Is this the first time you’ve seen this error? (Y/N): Yes, this is a new install

Steps to replicate it:

  1. Create a calendar that is shared with a group.
  2. Click on the listing of the calendar in the left hand menu

The output of your Nextcloud log in Admin > Logging: I don’t see any errors listed, and when I attempt to download the log file, I get an ‘internal server error’

do you have command line access to the server? access the data/nextcloud.log file directly
