Well i've this code into my .htaccess file

  Options +FollowSymlinks
    RewriteEngine on

    AddDefaultCharset UTF-8
    RewriteCond %{THE_REQUEST} ^[A-Z]+\ (.+)\.php  [NC]
    RewriteCond %{THE_REQUEST} !/?admincp/?((.)|(\.)*)
    RewriteRule [^/php/error\.php] /php/error.php  [L,NS]

    # Otherwise check if root request and rewrite to /php/index.php
    RewriteRule ^(/?)$ /php/index.php  [L,NS]
    RewriteCond %{THE_REQUEST} !\.php$  [NC]
    RewriteCond %{REQUEST_URI} !/?admincp/?((.)|(\.)*)
    RewriteRule ^([a-z|_]+)/?$ /php/index.php?categorie=$1 [L,NC,NS]
    RewriteCond %{THE_REQUEST} !\.php$  [NC]
    RewriteCond %{REQUEST_URI} !/?admincp/?(.*)
    RewriteRule ^([a-z|_]+)/([a-z|_|0|1|2|3|4|5|6|7|8|9]+)/?$ /php/index.php?categorie=$1&subcategorie=$2 [L,NC,NS]
    RewriteCond %{REQUEST_URI} !/?admincp/?(.*)
    RewriteCond %{THE_REQUEST} !\.php$  [NC]
    RewriteRule ^([a-z|_]+)/([a-z|_|0|1|2|3|4|5|6|7|8|9]+)/([^/]+)\.html$ /php/index.php?categorie=$1&subcategorie=$2&article=$3 [L,NC,NS]
    ErrorDocument 404 /php/index.php?categorie=apps&subcategorie=error404

I'm attempting to change line 6 for this:

  RewriteRule [^/php/index\.php\?categorie=apps&subcategorie=error404] /php/index.php?categorie=apps&subcategorie=error404  [L,NS]

however it does not work.. After i type http://localhost/php/index.php i check this out page, but i'd rather not check this out page..I wish to see http://localhost/php/index.php?categorie=apps&subcategorie=error404

Any help?
