Problem to instal :(

Hi,

I do everything from readme - all steps. When i paste to settings.php :

// ------------- BEGIN COPYING BELOW THIS LINE -------------
function custom_url_rewrite_outbound(&$path, &$options, $original_path) {

// Used by the Subdomain module to generate URLs with subdomains
if (module_exists('subdomain')) {
subdomain_url_rewrite_outbound($path, $options);
}
}

function custom_url_rewrite_inbound(&$result, $path, $path_language) {

// Used by the Subdomain module to correctly interpret URLs with subdomains
if (module_exists('subdomain')) {
subdomain_url_rewrite_inbound($result, $path, $path_language);
}
}
// ----------------- COPY UNTIL THIS LINE ------------------

I got 404 error

Where is the problem ?

Regards and thanks for help :)
