MySQL Error!

Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated column 'altfast.ru.dle_post.date' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

Error Number:

SELECT DATE_FORMAT(date,'%b %Y') AS m_date, COUNT(id) AS cnt FROM dle_post WHERE approve=1 AND date < '2018-06-18 02:04:56' GROUP BY m_date ORDER BY date desc
