Problème dans mon script php ??

Bonjour,

j'ai un problème dans mon script php et voici le message d'erreur :

Warning: usort(): Invalid comparison function. in /homepages/46/d149009739/htdocs/include/class/bbcode.inc.php on line 183

Tout fonctionne parfaitement mais J'ai ce message qui s'affiche dans le haut de la page et c'est plutôt génant, quelqu'un pourrait-il m'aider S.V.P ?

voici la page complète :
