BuddyPress.org

I’m trying to add a new tab to the profile page on Buddypress, I’ve successfully added the page, but when I click on the tab it returns “Permission Denied. Not Found / No Access”. I’m using a child theme of BuddyPress Social, here’s the code I’m trying to use:

add_action( 'bp_setup_nav', 'my_test_setup_nav' );
function my_test_setup_nav() {
    global $bp;

    $parent_slug = 'style';
    $child_slug = 'style_sub';

    //name, slug, screen, position, default subnav
    bp_core_new_nav_item( array( 
        'name' => __( 'Test' ), 
        'slug' => 'test', 
        'parent_url' => $bp->loggedin_user->domain . $bp->slug . '/', 
        'parent_slug' => $bp->slug, 
        'screen_function' => 'my_profile_page_function_to_show_screen', 
        'position' => 40
    ) );

    function my_profile_page_function_to_show_screen() {
        //add title and content here - last is to call the members plugin.php template
        add_action( 'bp_template_title', 'my_profile_page_function_to_show_screen_title' );
        add_action( 'bp_template_content', 'my_profile_page_function_to_show_screen_content' );

        bp_core_load_template( apply_filters( 'bp_core_template_plugin', 'members/single/plugins' ) );
    }

    function my_profile_page_function_to_show_screen_title() {
        echo '<div style="text-align:left;">Test Page</div>';
    }
    function my_profile_page_function_to_show_screen_content() { 
        echo '<div>hello world!</div>';
    }
}
