Redirect product page problem

Hi,

I’m using WooCommerce and i have a problem for 2 – 3 days, i don’t know what i change in woocommerce settings.

when I click on a product in the store, I am redirected to the order page instead of being redirected to the detail page of the product.

Here the link of the store : http://prepaecn.conferencesinternat.fr/boutique/

[ No bumping please. ]
