The Session settings are correct...still nothing.

hmm...when I changed "Shopping Cart Box Status" to always true and I click on the shopping cart box, it brings me to the cart correctly.

However, when I click buy now, or add to cart, it still brings me to a blank page. Pressing the back button on the browser though, my cart correctly added the item. And when I click on shopping cart, the item is correctly reflected. Clicking on Checkout throws me to another blank page.

I also noticed that with a full shopping cart, if I click on the links in the products category, the cart is correctly reflected. But when I click on home, or the page logo, the cart gets mysteriously emptied.

Home I making sense. Any help?
