Page "test%2test" could not be found

[gosys]

Website works but when i’m in the panel and want to edit a page then I get this message:

Page “instituut%2test” could not be found

link is: https://domain/panel/pages/instituut+test

How to solve this?

Kirby-3.5.7.1 with PHP 8.0

Hm, does this happen with all pages? Or just subpages? All subpages or just some? Can you reproduce the issue with a fresh starterkit of that same Kirby version?

Given that your are using a very old Kirby version, did this suddenly pop up and if so, after doing what?

I’m not familiar with Kirby. I transferred the website to another server, and everything looked fine until they tried to edit pages.
I can create a page, and it appears in the overview, but I can’t edit or delete it.
Site is: https://wimcrouwelinstituut.nl/en/instituut/about

So it worked fine on the original server, maybe some server config settings.

I’ve updated Kirby to 4.4.1 with PHP 8.2, but unfortunately, the error persists. Can you explain which config file I need to edit?
The old server was hit by ransomware, so everything on it is gone.
