BuddyPress.org

hello everybody

i’m tryying to make some pages of my website as tabs and subtabs of buddypress ,, i added some code to the functions.php of my theme and the tabs appeared but when i click it it goes to 404 page, and when i look at the url it gives a different one ,,,,,,,

[mod: link removed] http localhost doesn’t work on internet!
here is the code i’m using :

add_action('bp_setup_nav', 'create_tab1', 301 );
function create_tab1() {
   global $bp;
   bp_core_new_nav_item(
	array(
        'name' => 'test',
        'slug' => 'test', 
        'position' => 11, 
        'default_subnav_slug' => 'test', // We add this submenu item below 
        'show_for_displayed_user' => false,
        )
   );
}

thanks for your help
