problem in sorting users' points .

Good news, I found the issue. It turns out I am trying to adjust the wrong query leading to the user list being sorted according to user_login and not points.

I will include a fix in the next update, till then you can fix it by changing the following in the mycred-admin.php file located in /mycred/includes/

On line 44 change:

add_action( 'pre_get_posts', array( $this, 'sort_by_points' ) );

to:

add_action( 'pre_user_query', array( $this, 'sort_by_points' ) );

And on line 143 change:

/**
 * Sort by Points
 * @since 1.2
 * @version 1.0
 */
public function sort_by_points( $query ) {
	if ( !is_admin() ) return;
	$screen = get_current_screen();
	if ( $screen->id != 'users' || !isset( $query->orderby ) ) return;

	$orderby = $query->get( 'orderby' );
	if ( 'mycred' == $oderby ) {
		$query->set( 'meta_key', $this->core->get_cred_id() );
		$query->set( 'orderby', 'meta_value_num' );
	}
}

To:

/**
 * Sort by Points
 * @since 1.2
 * @version 1.1
 */
public function sort_by_points( $query ) {
	if ( !is_admin() ) return;
	$screen = get_current_screen();
	if ( $screen->id != 'users' ) return;

	$orderby = $query->get( 'orderby' );
	if ( 'mycred' == $orderby ) {
		global $wpdb;
		$cred_id = $this->core->get_cred_id();
		$order = $query->get( 'order' );
		$query->query_from .= " LEFT JOIN {$wpdb->usermeta} ON ({$wpdb->users}.ID = {$wpdb->usermeta}.user_id AND {$wpdb->usermeta}.meta_key = '$cred_id')";
		$query->query_orderby = "ORDER BY {$wpdb->usermeta}.meta_value+0 $order ";
	}
}
