layout from live chat on this theme update and shop page

How are ya? Here is the site http://bit.ly/1VWSBjq and here is the history of what it did look like http://bit.ly/1pLu4zX How can we remove the sidebar and get products to look the exact same and not different sizes like it was?

Of course, would love to fix other areas...this happened after a WooCommerce update on the theme too.
