Salut à vous tous du forum quelqu’un pourrait m’aider j’ai une erreur dans ma page accueil voilà ce qu’il y a écrit dans la fenêtre :
Ligne 208 Erreur :-‘ sereenplayer. Temp FaddingNode. Firstchild à la valeur Nul ou n’est pas un objet
J’ai fait un debogage mais je n’arrive pas aller plus loin merci de bien vouloir m’aider ( tres legé en informatique)
