WooCommerce display error

Hi Everyone,

Since the woocommerce update to 2.5 my products featured images do not appear anymore, instead I have two times the price displayed. Also, when you click on any product, it just opens a blank page and you cannot preview the product. If you would like to have a look this page will be the best example:
http://heritage-antiques.co.uk/antiques-2/

I have checked the display settings, it is all normal. I believe I might have done something when overriding templates in the theme file.

Has anyone got an idea of what I would need to do to solve this?

Thanks
