После того, как обновил MySQL до 5.7 получил ошибку:
Цитата:
Expression #3 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'doska.eboard_counter_cr.counter' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
Warning: mysqli_fetch_assoc() expects parameter 1 to be mysqli_result, boolean given in /var/www/vasya/data/www/сайт/includes/compile/functions.php on line 1
Expression #3 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'doska.eboard_counter_cr.counter' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
Эта же ошибка выскочила и на другой доске. На этом же сервере, есть сайты на wordpress, opencart, xenforo - с ними всё OK!
Где копать?
