Hi there, I updated from mediawiki 1.26 to 1.27 and since this, (new) articles don't show up in categories.
If I create a new article, or if I add a [[Category:foo]] to an existent article, these articles won't show up in Category:Foo's list of pages. Existing pages (which have been put into categories before 1.27) still show up. Only new added articles won't show up.
I don't see any error messages either.
