Debogage Module Sitemap 3.0.3 sur Prestashop 1.5.4

Bonjour,

Nous avons 2 sites web sous prestashop 1.5.4.1 utilisant le même module de sitemap "gsitemap 3.0.3" . Pour l'un des 2 sites, lors de la génération du sitemap, nous avons ce rapport d'erreur

Unknown column 'c.indexation' in 'where clause'

SELECT c.`id_cms` FROM `ps_cms` c INNER JOIN `ps_cms_lang` cl ON c.`id_cms` = cl.`id_cms` INNER JOIN `ps_cms_shop` cs ON c.`id_cms` = cs.`id_cms` INNER JOIN `ps_cms_category` cc ON c.id_cms_category = cc.id_cms_category AND cc.active = 1
WHERE c.`active` =1 AND c.`indexation` =1 AND c.`id_cms` >= 0 AND cs.id_shop = 1 AND cl.`id_lang` = 2 ORDER BY c.`id_cms` ASC
