My shop page has an error. I use WooComerce.

Hi there,

I am not sure if this is anything you guys can help with, but I am going to ask anyway. My shop page has an error on it and a developer said it is probably the fault of WooComerce, but since it is a free Plugin WooThemes will not help me trouble shoot.

The page does not want to cooperate. When I run Debug i get the following error that will not allow the products to load.

Fatal error: Call to a member function is_visible() on a non-object in /nas/wp/www/cluster-1454/marketequine/wp-content/plugins/woocommerce/templates/content-product.php on line 25

Is this anything you guys can help with? If not, anyone know somewhere or someone who could?
