Problem with FPDF

What about Friends very good night, I have a small problem with the FPDF tool on my website, the thing is that in localhost everything works perfectly, but by taking my php to the online hosting and request the pdf the page stays in White completely without printing any results or errors.

my php code is as follows:

<? @$id = @$_GET['id']; ?>
 <?

include('config.php');

@$userid = $_SESSION["id_usuario"];

$link=Conectarse();

 $query = "SELECT * from orders WHERE 'id' = '$id' ORDER BY 'orders'.'id' DESC";     // Esta linea hace la consulta 
    $result = mysql_query($query);
   $registro = mysql_fetch_array($result);
   $factura = $registro['id']; 
   $cantidad = $registro['cantidad']; 
   $cprod = $registro['cprod'];
   $pbase = $registro['pbase'];
   $cenvio = $registro['cenvio'];
   $costo = $cantidad * $pbase;
   $envio  = $cantidad * $cenvio;
   $producto = $registro['producto']; 
   $sum = $pbase + $cenvio;
   $total = $sum * $cantidad; 

?>
<?
    $cid = $registro['cid'];
    $consulta = "SELECT * FROM clientes WHERE 'id' = '$cid'";
    $query2 = mysql_query($consulta);
    $array = mysql_fetch_array($query2);
    $establecimiento = $array['establecimiento'];
    $calle = $array['calle'];
    $numero = $array['numero'];
    $colonia = $array['colonia'];
    $cd = $array['ciudad'];

    $consulta3 = "SELECT * FROM regiones WHERE 'id' = '$cd'";
    $query3 = mysql_query($consulta3);
    $array3 = mysql_fetch_array($query3);
    $ciudad = $array3['ciudad'];
    $estado = $array3['estado'];

    $consulta4 = "SELECT * FROM productos WHERE 'id' = '$producto'";
    $query4 = mysql_query($consulta4);
    $array4 = mysql_fetch_array($query4);
    $nproducto = $array4['nombre'];

    ?>
<?php
require('fpdf/fpdf.php');

$pdf=new FPDF();
///var_dump(get_class_methods($pdf));

$pdf->AddPage();

$pdf->SetFont("Arial","B","13");
$pdf->Cell(0,10,"Cerveceria Montoro SA. de CV.",0,0,"L");
