Unable to open WampServer's config file, please change path in index.php file

Dear All WordPress Master, saya mau minta tolong nih ada error, begini ceritanya.
Saya menggunakan wordpress 3.4.1, saya tidak menggunakan hosting gratis. Saya sudah upload folder wp (wordpress) ke www, jadi www\wp dan database(sql scritpnya) juga sudah di upload,
tapi setelah di panggil alamat webnya exit.web.id keluar tulisan “Unable to open WampServer’s config file, please change path in index.php file” Pada saat di localhost tidak ada masalah alias berjalan normal, apakah;
1. ada bagian lagi yang perlu di setting lagi setelah di upload?
2. bagaimana caranya?
maklum newbie dan my 1st site 🙂

isi index.php
<?php
/**
* Front to the WordPress application. This file doesn’t do anything, but loads
* wp-blog-header.php which does and tells WordPress to load the theme.
*
* @package WordPress
*/

/**
* Tells WordPress to load the WordPress theme and output it.
*
* @var bool
*/
define(‘WP_USE_THEMES’, true);

/** Loads the WordPress Environment and Template */
require(‘./wp-blog-header.php’);

isi .htaccess
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /wp/
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /wp/index.php [L]
</IfModule>

# END WordPress

Thanks B4.
