Problem with categories' URL ...

Hi there,

On my website, specialised on e-business for wood works: http://www.boutique-capalouest.eu

I have a problem with the URL for the categories. I have written the short URL on the admin page, but some trouble remain. For example, when I click on a category, "/epages/303374.sf/fr_FR/?ObjectPath=/Shops/303374/Categories" appears ...

Do it exist a solution to make disappearing this on the URL ?
