[PLUGIN: WOOCOMMERCE] Theme breaks the checkout page.

I have the latest version of wp and wc,the pages were installed by wc, I’ve checked that the shortcodes are correct, and I’ve made sure that there isn’t any template overrides going on.

The checkout page does this http://pawboss.com/checkout/

It just doesn’t display the checkout page at all.

I know that my theme is breaking it because it works fine on the twentyfifteen theme. I just don’t know what is causing the break.

Any ideas or help would be much appreciated.
