new server - Url changes, content of page doesn't - htaccess

[eluser]keld[/eluser]
Hi all,

I'm working on site for a friend, I was developing it on a server hosted by bluehost and now I tried to push it live on a server hosted by OVH, I see the home page fine but when I use the navigation, the url changes but the content of the page stays the same, anyone knows why? I'm 99% sure it's the htaccess, but what causes this?
My htaccess is very simple and works with bluehost:

Code:

RewriteEngine on
RewriteCond $1 !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]

I looked on google but couldnl't find anything, I used different htaccess that people posted on this forum but nothing works...
Please help,

Thank you
