[PrestaShopDatabaseException]

Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'filtershopgr_shop.cl.link_rewrite' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

		SELECT c.id_cms, cl.link_rewrite, cl.meta_title
		FROM ps_cms c
		LEFT JOIN ps_cms_lang cl ON (c.id_cms = cl.id_cms AND cl.id_lang = 2)
		 INNER JOIN ps_cms_shop cms_shop
		ON (cms_shop.id_cms = c.id_cms AND cms_shop.id_shop = 1)
		WHERE 1
		 AND c.id_cms IN (1) AND c.`active` = 1 GROUP BY c.id_cms
		ORDER BY c.`position`
