Checkout page not loading!

[ribbonsbaskets0]

Im moving away from working on the template to working on the checkout process. I finally input my API Signature and the such in admin. Originally I was able to get to the "create a user account" screen, created a new user and got to the checkout process. Now I cant even do that, when I "add item to cart" im brought to a blank screen. Can someone possibly tell me what happed, I might have done something while working with the php files and such but I dont think so.

Grab a copy of the Debug Utility from the Free Software Add-ons Tab and let it do it's magic for you.

I downloaded and tried it out with no success. It didnt create the log, I enabled full read on Cache and put the php in the correct sub folder.

Is there some file I might be missing or a specific file that calls on that login page to get to checkout...that might sound dumb

Also I forgot to add my link, its www.ribbonsbaskets.com/Cart

I orginaly had www.ribbonsbaskets.com Im trying to get the shopping cart to look like my original design, and of course finished off.

Does anyone know what would make the checkout page not work after you add an item to the cart. It worked when I orginally installed the shopping system. Check out the problem for your self www.ribbonsbaskets.com/Cart

I fixed it by loading the original header.php file. This fixed it.
