Prova cosi':

$sql="SELECT nickname,pwd,livello FROM utente 
      WHERE nickname='$user' and pwd ='$pass'";
           
$count=mysql_num_rows($ris);
    
if($count == 1){
   $row=mysql_fetch_assoc($ris);
   } else { 
           exit("login non corretto";) 
           }

if($row["livello"] == 'Esterno') {     
    $_SESSION["sess_var"] = "2";     
    header("location:menu_livello_2.php");
    exit;              
    } elseif($row["livello"]=='Interno') {          
        $_SESSION["sess_var"] = "3";     
        header("location:menu_livello_3.php");
        exit;             
        } elseif($row["livello"]=='Amministratore'){             
             $_SESSION["sess_var"] = "4"; 
             header("location:menu_livello_4.php");
             exit;           
             } else {            
                     header("location:menu.html");
                     exit;
                     }
