Hello, (sorry for my poor english, i speack french...)
I want to create et different page model:
- One with sidebar1 and sidebar2
- On without sidebar2
- And perhaps another without sidebar1 and 2 but with headmenu

I dont see page.php, article.php, etc. where i can put this code to create one page model:
<?php
/*
Template Name: Page001
*/
?>

Can you help me?

(can i make a backup of all settings of my thème?)

Thank you

at ATO->Style & configure SIDEBARS you control what pages the sidebars will display on

Thank You
