Not Found
The requested URL /Types_de-_soin.html was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.


Now if I want publish my page I just can see my oldest page
Someone help me
Thanks

It gives you 404 error, because

you have http://www.reiki-soins-a-distance.co..._de-_soin.html
as link for the button,

whereas on the server, you have

http://www.reiki-soins-a-distance.co...s_de_soin.html

Also, the menu should fall the same place on all pages, just to be consistent.
