Product page not working anymore

Hey guys,

some weeks ago I used woocommerce without any problems. But today I have rechecked my product page and there is absolutely no option to add it to your cart etc.

I think it stopped working after the latest WooCommerce update, but Im not 100% sure, since I havent checked it for 2-3 weeks now.
