[Errors] php

Hallo, Dus ik volgde een tutorial.

Maar stuiterde op het volgende probleem.

Ik heb dus een header, ((login/member beheer header) in de top van mijn pagina.

Maar. Ipv dat hij die header weergeeft.

Geeft hij 2 errors.

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/u638112868/public_html/index.php:11) in /home/u638112868/public_html/index.php on line 38


Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/u638112868/public_html/index.php:11) in /home/u638112868/public_html/index.php on line 38

En dit is het script, waarop het eerste zicht niks fout aan blijkt te zijn.

<?
ob_start();
session_start( );
require_once($_SERVER['DOCUMENT_ROOT'].'/db_connect.php');


 if ($_SESSION['logged_in'] != 1 && isset($_COOKIE['login_cookie'])) {
    list($user, $pass) = explode('[]', $_COOKIE['login_cookie']);
     $qu = mysql_query("SELECT `user_password` FROM `members` WHERE `username` = '".addslashes($user)."'");
    if (mysql_num_rows($qu) == 1) {
        $passw = mysql_fetch_object($qu);
        if ($passw->user_password == $pass) {
          $_SESSION['logged_in'] = 1;
           $_SESSION['username'] = $user;
            $_SESSION['password'] = $pass;
        }
    }
 }
if(!isset($_SESSION['username']) && !isset($_SESSION['password'])) {
   $_SESSION['logged_in'] = 0;
   $user = "Guest"; 
 }
?>

Dus ik zou het erg waarderen, als iemand wist wat hier fout aan is.

Ehm.

Dit is de header, die ik op elke pagina moet plaatsen.

Mvg, Fabio

edit;

session_start();

<<< Dit is die Line 38

Wel, Verder in de index.php pagina, heb ik deze ook nog staan.
