[PrestaShopDatabaseException]

Expression #3 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'filtershopgr_shop.ps_layered_category.filter_show_limit' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

			SELECT type, id_value, filter_show_limit, filter_type FROM ps_layered_category
			WHERE id_category = 27
				AND id_shop = 1
			GROUP BY `type`, id_value ORDER BY position ASC
