I've just installed the latest version of eCommerce. Product pages, add to cart etc are working fine. When i select 'Go to checkout' it returns a HTTP 500 Internal Server Error - website cannot display the page.
When i change the 'checkout' page type to just 'page' it displays just a normal page, so the error must be within the 'checkoutpage' code. I've downloaded it straight from the SilverStripe site without altering any code yet so can't figure out why it's not working.
