Joomla/phpbb bug

Bonjour, J'ai un problem avec mon site eb. au début j'ai installé phpbb3, le forum à tourner pendant 4 mois puis là j'ai installé Joomla. donc ayant changer la prsentation de mon site, mon forum ne saffiche plus à l'adress www.monsite.com mais à www.monsite.com/forum

Tout ce passait très bien jusqu'au jour ou j'ai voulu installé le bridge pr joomla/phpbb. J'ai pas réussi dc j'ai supprimé tous les fichiers que javais installé du ridge dont auth-joomla. le forum apparit bien mais à la moindre modif voici j'ai ce message:
