Try this, it worked for me!

function custom_setup_nav() {
global $bp;

bp_core_new_nav_item( array(
‘name’ => __( ‘About’, ‘buddypress’ ),
‘slug’ => ‘about’,
‘position’ => 30,
show_for_displayed_user’ => true,
‘default_subnav_slug’ => ‘about’,
‘item_css_id’ => ‘about’
) );
}

bp_core_new_subnav_item(
array( ‘name’ => __( ‘About’, ‘buddypress’ ),
‘slug’ => ‘about’,
‘parent_url’ => $bp->loggedin_user->domain . ‘about’,
‘screen_function’ => ‘about’,
‘parent_slug’ => ‘about’,
‘position’ => 10,
‘item_css_id’ => ‘about’
)
);

add_action( ‘bp_setup_nav’, ‘custom_setup_nav’ );

function about_page() {
add_action( ‘bp_template_content’, ‘about_content’ );
bp_core_load_template( apply_filters( ‘bp_core_template_plugin’, ‘members/single/about’ ) );
}

function about_content(){
//Put your content here!
}
