What am I doing wrong on this query? The main issue is the var_dump returns null. The query works fine in phpMyAdmin.

global $wpdb;
$users = $wpdb->get_results(
            u.ID AS id, 
            u.user_login AS name,
            AVG(b.star) AS rating, 
            COUNT(b.star) AS reviews,
            m.meta_value AS roles
            wp_users AS u
                LEFT JOIN
            wp_usermeta AS m ON u.ID = m.user_id
                LEFT JOIN
            wp_bp_activity AS b ON u.ID = b.usercheck
            (m.meta_key = 'wp_capabilities' AND m.meta_value LIKE '%subscriber%') 
            (b.is_activated is null or b.is_activated = 1)
        GROUP BY u.ID
        ORDER BY reviews DESC
        LIMIT %d", $limit
return var_dump($users);

Be careful with the '%subscriber%' part, inside the wpdb::prepare() method.

Use '%%subscriber%%' instead.

Otherwise $limit will match the %s part and the %d part will be unmatched.
