Woocommerce Pages structure

I am having issues with the checkout page of my site, nothing will load on that page upon checkout.

I am wondering the structure of all of the pages in the woocommerce plugin pages tab.

Should all of these pages be children of the page I have assigned as my shop?

I cannot for the life of me figure out why nothing is loading on my checkout page. I have checked the PHP memory, page shortcodes, disabling plugins etc.. nothing seems to work.

Any ideas?

Thanks
