[Problème] Problème accès gestion utilisateur - Erreur 500

[pelucre]

Bonjour ,

Je tourne sous joomla 2.5 avec community Builder 1.8 et Virtuemart 2.0.2. Dés que j'essaye d'accéder à la gestion des utilisateurs, une erreur 500 apparait :

Table 'BDD_prefixe_user_notes' doesn't exist SQL=SELECT n.user_id, COUNT(n.id) As note_count FROM prefixe_user_notes AS n WHERE n.user_id IN (43,42,44,45) AND n.state >= 0 GROUP BY n.user_id

De même si je tente d'accèder à Gestion des Utilisateurs>Niveau d'accès>Notes des Utilisateurs " , l'erreur 500 apparait :

Table 'BDD_prefixe_user_notes' doesn't exist SQL=SELECT a.id, a.subject, a.checked_out, a.checked_out_time,a.catid, a.created_time, a.review_time,a.state, a.publish_up, a.publish_down,c.title AS category_title, c.params AS category_params,u.name AS user_name,uc.name AS editor FROM prefixe_user_notes AS a LEFT JOIN prefixe_categories AS c ON c.id = a.catid LEFT JOIN prefixe_users AS u ON u.id = a.user_id LEFT JOIN prefixe_users AS uc ON uc.id = a.checked_out WHERE (a.state IN (0, 1)) ORDER BY a.review_time DESC Table 'BDD_prefixe_user_notes' doesn't exist SQL=SELECT a.id, a.subject, a.checked_out, a.checked_out_time,a.catid, a.created_time, a.review_time,a.state, a.publish_up, a.publish_down,c.title AS category_title, c.params AS category_params,u.name AS user_name,uc.name AS editor FROM prefixe_user_notes AS a LEFT JOIN prefixe_categories AS c ON c.id = a.catid LEFT JOIN prefixe_users AS u ON u.id = a.user_id LEFT JOIN prefixe_users AS uc ON uc.id = a.checked_out WHERE (a.state IN (0, 1)) ORDER BY a.review_time DESC LIMIT 0, 20 Table 'BDD_prefixe_user_notes' doesn't exist SQL=SELECT a.id, a.subject, a.checked_out, a.checked_out_time,a.catid, a.created_time, a.review_time,a.state, a.publish_up, a.publish_down,c.title AS category_title, c.params AS category_params,u.name AS user_name,uc.name AS editor FROM prefixe_user_notes AS a LEFT JOIN prefixe_categories AS c ON c.id = a.catid LEFT JOIN prefixe_users AS u ON u.id = a.user_id LEFT JOIN prefixe_users AS uc ON uc.id = a.checked_out WHERE (a.state IN (0, 1)) ORDER BY a.review_time DESC

Je me doute fortement qu'il me manque des tables mais je ne sais pas quelle requête SQL passer pour les réinstaller.

Merci d'avance pour votre aide
