Funciones sesion y header
Hola estoy creando una nueva aplicacion en php y me da un error en la pagina de login el siguiente
Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at C:\wamp\www\contemplate\Paginas\login.php:1) in C:\wamp\www\contemplate\Paginas\clases.php on line 68.
Este es el codigo de la pagina login:

<?php
include("clases.php");
$temp=new Reportes();
$temp->AbrirSesion();

if(isset($_POST['usuario'])&& isset($_POST['contrasenna']))
{
include("clases.php");
$temp=new Reportes();
$temp->Connection('localhost','reportesphp','root','') ;
$result= $temp->RestringirAcceso($_POST['usuario'],$_POST['contrasenna']);
$cantidad=mysql_num_rows($result);
echo $cantidad;
//mysql_free_result($result);
//mysql_close();

if($cantidad>0){
$fila=mysql_fetch_row($result);
//$_SESSION['MM_Username'] = $fila[0];
//$GLOBALS['MM_Username'] = $fila[0];
//session_register("MM_Username");
//echo MM_Username;

//header ("location:RegistrarReporte.php");

}
/*else{
header("location:login.php");
}*/
}
?>
