Thank you very much for your answer.

I’m not sure I understood correctly.

Finally it is especially that when I create a child template for this page, it always comes back to Home.

At line 13 there is this:

if (! (is_front_page ()) &&! is_page_template ('templates / home.php')) {
     return;
}

Should I add is_page(9742)?

Thanks a lot for your help
