Expression #8 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'auuecom2_boxbanner.com.br.bad_n_ad.ad' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

select bad_users.username,bad_users.u1,bad_users.u2,bad_users.u3,bad_users.u4,bad_users.u5,bad_users.joined,bad_n_ad.ad,bad_n_ad.ad_n from bad_users,bad_n_ad where bad_n_ad.accept = '1' AND bad_n_ad.approv = '1' AND bad_n_ad.enabl = '1' AND bad_n_ad.ad != '' AND bad_users.suspended = 0 AND bad_n_ad.size = '1' AND bad_n_ad.user = bad_users.n AND bad_users.n = bad_n_ad.user group by bad_users.n,bad_n_ad.ad_n
