Bad Rediriction n BuddyPress

Hello
I try to make a Slug Page for BuddyPress but i got a Bad Redirection.

I make a new item menu name Item One with this code `function my_setup_nav() {

global $bp;

bp_core_new_nav_item( array(

‘name’ => __( ‘Item One’, ‘buddypress’ ),

‘slug’ => ‘my-item-one’,

‘position’ => 30,

‘screen_function’ => ‘my_item_one_page’,

) );

}

add_action( ‘bp_setup_nav’, ‘my_setup_nav’ );

function my_item_one_page() {

bp_core_load_template( ‘item-one-template’ );

}

`

After I make a slug page name : item-one-template.php than i put in my Child Theme.

I copy paste the template Buddypress.php inside.

I i don’t put this file i got a 404 error and if i put this file in my child theme i got a bad rediction
in the members search page.
So i can’t edit my template for this slug.
Do you know why ?

thanks 🙂
