MySQL Error!

The Error returned was:
Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated column 'dleinua9.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:
1055

SELECT DATE_FORMAT(date,'%b %Y') AS m_date, COUNT(id) AS cnt FROM dle_post WHERE approve AND date < '2018-07-15 22:55:24' GROUP BY m_date ORDER BY date desc
