why the list of pages does not appear in my categories pages (mediawiki)?

Question

This page : https://www.mediawiki.org/wiki/Help:Categories

State that : Each of the pages in the Category namespace represents a so-called category, a grouping of related pages, and contains an index for the pages of its category.

Mine do not !

If I add a [[Category:mycat]] in an article and save it, mycat appear in the category list widget. But if I clic the link and create the new category page, I do not have any article list.

Do I Forget something ?

I am on the "latest" library/mediawiki docker image, with the "timeless" skin and a sqllite database.

Answer 1

I do not know what was the problem, but the last Docker image version work out of the box ...
