Thema: Fehler Content Menue

Hallo zusammen,

habe im Backend ein Problem. Wenn ich im menue content / all content typs aufrufe kommt folgende Fehler meldung. lst das ein Installationsfehler ? benutze Mambo 4.5.2
sonst läuft alles reibungslos

DB function failed with error number 1054
Unknown column 'c.access' in 'on clause' SQL=SELECT c.*, g.name AS groupname, cc.name, u.name AS editor, f.content_id AS frontpage, s.title AS section_name, v.name AS author FROM mos_content AS c, mos_categories AS cc, mos_sections AS s LEFT JOIN mos_groups AS g ON g.id = c.access LEFT JOIN mos_users AS u ON u.id = c.checked_out LEFT JOIN mos_users AS v ON v.id = c.created_by LEFT JOIN mos_content_frontpage AS f ON f.content_id = c.id WHERE c.state >= 0 AND c.catid=cc.id AND cc.section=s.id AND s.scope='content' ORDER BY s.title, c.catid, cc.ordering, cc.title, c.ordering LIMIT 0,10




vielen Dank für eine Anregung
