Normalement, il faut passer par le formulaire de demande de conversion gratuite situé dans le menu help en haut des pages du site, et en particulier s’assurer d’avoir respecté tout ce qui est demandé dans la checklist (càd pas seulement le listing mais aussi images du résultat attendu, descrption, etc…):
https://www.prorealcode.com/free-code-conversion/
Dans ce cas particulier au vu du titre, il est possible que cela ait déjà été converti, ou déjà publié sans conversion. Le moteur de recherche permettra de vérifier, il est situé en haut à droite, en passant la souris sur son avatar pour faire apparaitre un menu déroulant, où il est placé en première ligne, cf image attachée.
Si pas déjà converti, plutôt que de recréer un autre sujet depuis le formulaire, merci de poster ici les éléments manquants (images etc…) dans le présent sujet démarré.
