elimination of the index.php [Problem solved]

Hello,

I followed not badly of tutorial for the configuration but in my URL I always have the index.php present.

here my file .htacess

PHP Code:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L] 


here my file config.php

PHP Code:

$config['base_url']    = "http://www.leleu-nom.fr";





/*
|--------------------------------------------------------------------------
| Index File
|--------------------------------------------------------------------------
|
| Typically this will be your index.php file, unless you've renamed it to
| something else. If you are using mod_rewrite to remove the page set this
| variable so that it is blank.
|
*/
$config['index_page'] = '';

/* 


and the example of a URL : http://www.leleu-nom.fr/index.php/homepage/curriculum
