[Forum] Problème avec Forum/include/functions.php

Bonjour,

Depuis le temps que je ne suis pas venu ici, je me devais de faire mon retour.

J'ai crée un forum en fluxbb sur Free. Tout fonctionnait bien, jusqu'à que j'apporte des modifications à certains fichiers afin d'améliorer le forum.

J'ai donc en premier lieu rajouté l'option pour les anniversaires. Tout fonctionnait.
Puis j'ai décidé de rajouter à ce forum l'option des réponses rapides.
Et c'est là que ça foire.
Depuis que j'ai modifié les fichiers, voici ce que ma page d'accueil m'affiche :

"Parse error: syntax error, unexpected $end in /mnt/154/sda/1/3/atp71/forum/include/functions.php on line 2094"

Voici le contenu de la page concernée, je ne localise pas le problème, bien qu'il m'indique une ligne inexistante (la dernière ligne est 2093).

Comment régler ce problème afin que je puisse remettre le forum en fonction ?

Merci d'avance pour votre aide.

(J'ai supprimé les lignes du début)
