not loading

hi
i coded a software that was working fine last week. but i noticed that none of it's php fines is working. the pages are not loading. see this url for example
i was confused and thought maybe the php softwares on the server are not running properly, so tested a php file:
working.php:
<?php
echo "php is working";
?>
and you see it's working: click here to see
this software also uses pear and mysql codes
can you guess any reason?

 

cen you be more specific or post some example code.

 

in almost all of the pages that are not loaded (but were loading already) (like http://textly.fr/login.php ) this code is used on the top:
include 'global.php';
and global.php is:

<?php
/* $Id: global.php,v 1.65 2002/09/20 08:57:24 shaggy Exp $ */
session_start(); // keep above lib/user.php and functions.php
require_once 'functions.php';
require_once '../config.php'; // before session_defaults
require_once 'session_defaults.php';
require_once 'lib/user.php';
include 'error.php';
$db = db_connect();
$user = new User($db);
?>

PHP:

 

and config.php is:

<?php

function handlePearError($error) {
	header('HTTP/1.0 500 Internal Server Error');
	//die("$error->message<br />$error->userinfo"); // uncomment this to debug
	die('Error ocurred, please try again later');
}


function &db_connect() {
	require_once 'DB.php';
	$dsn = "mysql://root:@unix+localhost/adsense";

	$db = DB::connect($dsn);

	if (DB::isError($db)) {
		die("Database connection failed.");
	}

	$db->setFetchMode(DB_FETCHMODE_OBJECT);
	$db->setErrorHandling(PEAR_ERROR_CALLBACK, 'handlePearError');
	
	return $db;
}
?>
