title: Magento Checkout redirects to “Shopping cart is empty” page and clears cart in IE7 & IE8
body: <p>After adding products to the shopping cart and clicking “Checkout”, the OnePage Checkout page opens. It allows you to select whether to check out as a Guest or Registered User. After you have selected an option, it briefly shows up the “Billing Details” pane, before suddenly redirecting to another page which displays the message “Shopping Cart is empty”, and any items you had in your cart are removed. This problem is only occurring in Internet Explorer 8 and below. Website URL is <a href="http://tastesfromaroundnz.co.nz" rel="noreferrer">http://tastesfromaroundnz.co.nz</a> . Cookie lifetime is set to 86400, and all of the Session Validation Settings are set to “No”. Magento version is 1.6.2</p>
  
  <p>Anyone able to help us with this problem? Thanks in advance. </p>
