Плагин mantisBT Ошибка GaugeSupport # 1111: Неправильное использование групповой функции

Я использую mantisBT 1.2.19 для проекта отслеживания ошибок http://mantisbt.org/download.php.

Кроме того, я использую плагин gaugeSupport для поддержки пользовательских голосов за ошибки в рейтинге ошибок (https://github.com/EvilRenegade/Gauge-Support)

Плагин не работает правильно для моего проекта богомола:

В файле плагина Issue_ranking.php есть запрос MySQL:

$dbquery = "SELECT
max(sd.bugid) as bugid,
count(sd.rating) as no_of_ratings,
sum(sd.rating) as sum_of_ratings,
avg(sd.rating) as avg_rating,
max(sd.rating) as highest_rating,
min(sd.rating) as lowest_rating,
IFNULL(bm2_count,0) AS bm2_count,
IFNULL(bm2_sum,0) AS bm2_sum,
IFNULL(bm1_count,0) AS bm1_count,
IFNULL(bm1_sum,0) AS bm1_sum,
IFNULL(b2_count,0) AS b2_count,
IFNULL(b2_sum,0) AS b2_sum,
IFNULL(b1_count,0) AS b1_count,
IFNULL(b1_sum,0) AS b1_sum
FROM {$plugin_table} sd
INNER JOIN {$bug_table} b ON sd.bugid = b.id
LEFT OUTER JOIN (SELECT bugid, count(rating) as bm2_count, sum(rating) as bm2_sum FROM {$plugin_table} GROUP BY bugid, rating HAVING rating = -2) bm2 ON sd.bugid = bm2.bugid
LEFT OUTER JOIN (SELECT bugid, count(rating) as bm1_count, sum(rating) as bm1_sum FROM {$plugin_table} GROUP BY bugid, rating HAVING rating = -1) bm1 ON sd.bugid = bm1.bugid
LEFT OUTER JOIN (SELECT bugid, count(rating) as b2_count, sum(rating) as b2_sum FROM {$plugin_table} GROUP BY bugid, rating HAVING rating = 2) b2 ON sd.bugid = b2.bugid
LEFT OUTER JOIN (SELECT bugid, count(rating) as b1_count, sum(rating) as b1_sum FROM {$plugin_table} GROUP BY bugid, rating HAVING rating = 1) b1 ON sd.bugid = b1.bugid
{$where_clause}
GROUP BY sd.bugid
ORDER BY sum(sd.rating) {$order}
LIMIT {$start}{$noOfBugs}";

что приводит к ошибке:

Database query failed. Error received from database was #1054: Unknown column 'rating' in 'having clause' for the query:  SELECT
max(sd.bugid) as bugid,
count(sd.rating) as no_of_ratings,

GROUP BY sd.bugid

Когда я добавляю столбец «рейтинг» к запросу, я все еще получаю сообщение об ошибке неправильного использования функции GROUP BY:

Кто-нибудь знает, как правильно настроить плагин GaugeSupport для Mantis?

Спасибо!
