[PHPBB3] Lien vers bas de page qui ne marche pas

Bonjour,

sur mon forum en cours de construction, je note que dans la page des sujets les flèches qui renvoient vers le haut de page marchent bien mais pas celles qui renvoient vers le haut de page.
Le script (Milouze tu reocnnaitra surement ton script, c'est toi qui me l'avaiot intégré) vient fort probablement du Template Topicviewtopic_body qui est le seul à avoir été modifié.
De ce que j'ai pu voir malgré mes connaissances quasi nulle, ça semble etre lié au code #top #L_BACK_TO_TOP et #bottom #L_GOTO_DOWN

il doit y avoir un bug ou un oubli de repère du bas de page. Merci pour toute aide
voici un lien direct vers une page en question: https://coup-de-gueule.kanak.fr/t34-ceci-est-un-message-d-essai#87
Voici le code
Topicview_body
