Subpages redirect me to the homepage …

Hi!

This is my second problem. If i create pages, no problem, i can see them. But as soon as i create a subpage, if i try to go to that subpage, i’m redirected to the homepage of my website.

Example: http://projetsetudiants.fr/partenaires/proving-junior/

On the other hand, top level pages still works.

I can paste you my .htaccess:

RewriteEngine On

RewriteBase /

RewriteRule ^index.php$ – [L]

# uploaded files

RewriteRule ^files/(.+) wp-includes/ms-files.php?file=$1 [L]

RewriteCond %{REQUEST_FILENAME} -f [OR]

RewriteCond %{REQUEST_FILENAME} -d

RewriteRule ^ – [L]

RewriteRule . index.php [L]

That’s the default one i guess.

Thanks !
