How to configure the text of "Page not found" page

Infos:

  • Used Zammad version: 5.3.0-1670492123.7c45d087.buster
  • Used Zammad installation type: (source, package, docker-compose, …) package
  • Operating system: Debian 10.10
  • Browser + version:
    Chrome, Edge, Firefox, private windows, to no avail

Expected behavior:

  • We have some internal links that require user login before accessing. Public users should see something like login required

Actual behavior:

  • Page not found, The page you were looking for does not exist. [Click here] to go to the homepage.

Steps to reproduce the behavior:

Set the article as Internal and only login customer can access, when we use inprivate window to access the link, it shows Page not found. Is there a conf file we can edit from the backend to change the default text?

The not found text cannot be configured.

oh and…

especially this is not existing in Zammad.
