Description du problème

Bonjour,

j'ai bien suivi avec rigueur le tutoriel suivant : https://forum.forumactif.com/t373733-decorez-vos-forums-pour-les-fetes-de-fin-d-annee

mais le code javascript suivant ne fonctionne pas

Code:

        $(function() {
                $.getScript("http://illiweb.com/rs3/10/frm/snow.js");
            });

Quelqu'un peut-il m'aider ? Est ce du à l'invision?

Merci d'avance

En analysant le forum, je ne trouve pas de trace de ce js.

Vous avez activé les js dans votre pa ??

Dans le doute, voici un autre js pour les flocons de neige.

Bonjour,

Oui j'avais bien activé. J'ai essayé avec votre code et ça fonctionne correctement. Merci beaucoup
