probleme de passage de sandbox au mode live

[evrard1313]

Bonjour a tous, Voila je rencontre un petit problème avec mon code lors du passage de sandbox en mode live. En effet ayant change mon Client ID et mon Secret il ne marche toujours pas et ma page https://thelockedfile.com/payment.php est tout toute blanche comme si le code se refuse d'etre execute. Par contre ces memes codes fonctionnent sans aucun probleme en mode Sandbox. Voici mes differents codes :

subscribe.php

<?php
require 'inc/secret_header.php';
require 'inc/function.php';
require_once 'inc/db.php';
require 'inc/Offer.php';

logged_only();

if (isset($_POST['offer'])){

    $_SESSION['offer_key'] = $_POST['offer'];
    header('location: payment.php');
}

?>

<h3>S'abonner</h3>

<form action="" method="post" class="user">

    <ul>

        <?php foreach (Offer::getoffers() as $k => $offer😞 ?>
        <li><input type="radio" name="offer" value="<?= $k; ?>"><?= $offer['name']; ?> = <?= $offer['price_text']; ?></li>
        <?php endforeach; ?>

    </ul>

    <button class="btn btn-success" type="submit">S'Abonner</button>
