hello, sorry i didn’t find the answer ans i just sent my question again.
Thanks for the code, it works fine !
About the footer, it does only show the copyright and fb because i didn’t activate the widgets , i only activated the “bandeau” (i don’t know the english term : small line on the far bottom) .
But i need some widgets (legal mentions etc…) and, as soon as i put the widget thing on, the page list appears although it does NOT appear on my appearance>>widget dashboard.

hoping to be clear, thanks for your help!
