Some post don't display in single page

Hi,
I’m making a website for a client with wordpress Twentytwelve child Theme. I use a home page which displaying all the post I need with a parallax effect. Everything works, but when I want to show a post in single page I’ve got the 404 error page. And it occures with only 3 posts : restaurant, hotel, carte. I need to show post to single page in minileven mobile version.
The website is in test here
If someone have a clue, and sorry about the english
