"Leaders" isn't working

I have plenty of members with rated profiles and photos, yet none of them shows on the "leaders" block, neither for the month, week or day.

Is there a setting I'm missing?

I remember reading somewhere that three or more members must comment on the same image during the time period. Three people must vote on the same image, in the same day, for it to show up on the day... etc.

Is there anywhere where the setting of "how many must vote" can be changed?

Are you speaking of the "Point Leaders" block or the "Most Popular" block ???

No. I'm speaking of the block named "Leaders".

This setting can be changed by editing inc/classes/BxDolVotingQuery.php.

Look near bottom for: 

return $this->getOne ("SELECT $sTable.`{$sPre}id`, COUNT($sTable.`{$sPre}id`) AS `voting_count` FROM {$sTable} $sJoin WHERE TO_DAYS(NOW()) - TO_DAYS($sTable.`{$sPre}date`) <= $iDays $sWhere GROUP BY $sTable.`{$sPre}id` HAVING `voting_count` > 2 ORDER BY `voting_count` DESC LIMIT 1");

And change the voting_count number from 2 to 1 or 0.
