Error page invisible in panel

Hello, I have a blueprint with unlisted pages section, wich works fine but don’t list the error page. Did I miss something? how can I edit/translate the error page text in panel?

Also, is there a way to distinguish 404 from 403 errors ?


In the Starterkit, the error.yml has this setting:

title: Error

  read: false

which prevents reading of the page. If you remove that, your error page should reappear.

Ok thank you! (I was looking for a parameter in the error.txt page with no luck)
