Topic on Extension talk:Contribution Scores

In my installation, showing Special:ContributionScores throws the following error:

Error 1055: Expression #4 of SELECT list is not in GROUP BY clause and contains nonaggregated column 's.page_count' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

As a temporary workaround I can use:

$wgSQLMode="";

in LocalSettings.php.

The problem can probably be fixed changing line 188:

'GROUP BY' => 'user_name',

to

'GROUP BY' => 'user_name, page_count, rev_count',
