Bubbles: GROUP BY error

[forgetms]

ERROR:  column "u.email" must appear in the GROUP BY clause or be used in an aggregate function at character 8
STATEMENT:  SELECT u.email FROM users u
    LEFT JOIN bubbles b ON b.uid=u.id
    WHERE u.block='0' AND u.id <> '0'
    AND ((b.parent='52') OR (b.id = '52'))
    AND b.uid <> '0'
    GROUP BY u.id

Does replacing "GROUP BY" with "ORDER BY" at line 414 for bubbles.php fix the problem?

Add u.email In the group by clause:

GROUP BY u.id, u.email
