Expression #11 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'napmuc_dacsan.cl.id_lang' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
SELECT c.*, cl.id_lang, cl.name, cl.description, cl.link_rewrite, cl.meta_title, cl.meta_keywords, cl.meta_description FROM `bs_category` c LEFT JOIN `bs_category_lang` cl ON (c.`id_category` = cl.`id_category` ) WHERE `id_parent` = 1 AND `active` = 1 GROUP BY c.`id_category` ORDER BY `level_depth` ASC, c.`position` ASC
