erro 500 SQL=SELECT a.id, a.title, a.alias, a.note, a.published, a.access, a.checked_out, a.checked_out_time, a.created_user_id, a.path, a.parent_id, a.level, a.lft, a.rgt, a.type, a.core, a.required, a.edit, a.profile, a.register, a.search, a.language,l.title AS language_title,uc.name AS editor,ua.name AS author_name,ug.title AS access_title FROM db_jsn_fields AS a LEFT JOIN `db_languages` AS l ON l.lang_code = a.language LEFT JOIN db_users AS uc ON uc.id=a.checked_out LEFT JOIN db_users AS ua ON ua.id = a.created_user_id LEFT JOIN db_viewlevels AS ug on ug.id = a.access WHERE a.alias <> 'root' AND (a.published IN (0, 1)) ORDER BY a.lft asc LIMIT 0, 20
