Affichage (très) lent du forum

Bonjours,
Sur mon forum kunena on doit attendre 6 bonnes secondes (si ce n'est +) pour que chaque page s'affiche:
-quand on va sur une catégorie
-quand on veut créer un sujet
-quand on veut enregistré le sujet...etc

Est-ce que quelqu'un sais comment y remédier ? Lien du forum !
Merci d'avance

Bonjour,

Tu aurais un lien vers ton site ?

As-tu essayé de désactiver tous les modules/plugins tiers pour voir si le problème viendrait de là ?

Je ne peux pas activer Mootools Upgrade sinon mon template Yootemplate (Yoo Block) ne fonctionne pas...

Désactive tous les plugins/modules et re-active les uns par uns en testant kunena à chaque fois pour voir lequel pose souci.

Le problème semble venir du Motools Upgrate que je ne peux activer :S
Il faut donc que je trouve un moyen de l'activer
