File not found

Okay...

Actually, adding "index.php" to urls make the app running fin.

Why these lines in my .htaccess didn't do the job ? (this is the .htaccess initially stored in the public dir that I copied to my root dir)

Code:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
