please help with information menu sidebox

[Alborz]

guys, plz take a look and help me with this menu.

http://www.carpetstories.com/

you see there is a information menu sidebox, but I've no idea how to edit these pages,

if you click on "about us" , there is nothing to show and also for "about persian carpet" there is a 404 error!

in the admin area, I've used "define page editor" but the text I entered there for these two pages will not affect the frontend. still a blank page and a 404 error!

so how can I get this thing working?

tx in advance
