Problème mon site et l'administration affiche une page blanche

[Unatomisa]

Bonjour,

Lorsque je vais sur mon site et l'administration, j'ai une page blanche. Et dans config.inc.php j'ai activé le bug et j'ai ce message.

Fatal error: Undefined class name 'configuration' in /homez.99/meublitt/www/config/config.inc.php on line 61

Et ma ligne 61 correspond à : Configuration::loadConfiguration();

Mon code du config.inc.php :

<?php

/* Debug only */
@ini_set('display_errors', 'on');
define('_PS_DEBUG_SQL_', false);

/* Improve PHP configuration to prevent issues */
@ini_set('upload_max_filesize', '100M');
@ini_set('default_charset', 'utf-8');

/* Correct Apache charset */
header('Content-Type: text/html; charset=utf-8');

/* Autoload */
function __autoload($className)
{
if (!class_exists($className, false))
require_once(dirname(__FILE__).'/../classes/'.$className.'.php');
}

/* No settings file? goto installer...*/
if (!file_exists(dirname(__FILE__).'/settings.inc.php'))
{
$dir = ((is_dir($_SERVER['REQUEST_URI']) OR substr($_SERVER['REQUEST_URI'], -1) == '/') ? $_SERVER['REQUEST_URI'] :

dirname($_SERVER['REQUEST_URI']).'/');
if(!file_exists(dirname(__FILE__).'/../install'))
die('Error: \'install\' directory is missing');
Tools::redirect('install', $dir);
}
include(dirname(__FILE__).'/settings.inc.php');

/* Redefine REQUEST_URI if empty (on some webservers...) */
if (!isset($_SERVER['REQUEST_URI']) OR empty($_SERVER['REQUEST_URI']))
{
$_SERVER['REQUEST_URI'] = $_SERVER['SCRIPT_NAME'];
if (isset($_SERVER['QUERY_STRING']) AND !empty($_SERVER['QUERY_STRING']))
$_SERVER['REQUEST_URI'] .= '?'.$_SERVER['QUERY_STRING'];
}

/* Include all defines */
include(dirname(__FILE__).'/defines.inc.php');
/* Defines are not in defines.inc.php file for no conflicts in installer */
define('_PS_MAGIC_QUOTES_GPC_', get_magic_quotes_gpc());
define('_PS_MODULE_DIR_', _PS_ROOT_DIR_.'/modules/');
define('_PS_MYSQL_REAL_ESCAPE_STRING_', function_exists('mysql_real_escape_string'));

/* aliases */
function p($var) {
return (Tools:($var));
}
function d($var) {
Tools:($var);
}

global $_MODULES;
$_MODULES = array();

/* Globals */
global $defaultCountry;

/* Load all configuration keys */
Configuration::loadConfiguration();

/* Load all language definitions */
Language::loadLanguages();

/* Load all zone/tax relations */
Tax::loadTaxZones();

/* Loading default country */
$defaultCountry = new Country(intval(Configuration::get('PS_COUNTRY_DEFAULT')));


/*
* It is not safe to rely on the system's timezone settings, but we can\'t easily determine the user timezone and the use

of this function cause trouble for some configurations.
* This will generate a PHP Strict Standards notice. To fix it up, uncomment the following line.
*/
if (function_exists('date_default_timezone_set'))
{
$timezone = Tools::getTimezones(Configuration::get('PS_TIMEZONE'));
date_default_timezone_set($timezone);
}

/* Smarty */
include(dirname(__FILE__).'/smarty.config.inc.php');

J'ai beau chercher, mais je ne trouve pas du tout la solution.

Cordialement.
