After several tentatives, I installed Yoast and it did solve the issue.
I’ve already tried this procedure but it was unsuccessful 🙁
Hi Sabina,
thanks for your answer. Could this option be modified using the theme editor?

For completeness’ sake: my goal is to restrict the file visibility to a specific group of users, how should I do it?
I tried unsuccessfully to set its visibility as both public and private while allowing a specific group the permission to read it, but it always let anybody with the direct URL access it.
