Paypal Auto Redirect Not Working

Hi guys,

I've set up my selling preferences in Paypal to automatically return to my website once a successful payment has went through. However; all that happens is that a customer is displayed a Paypal success page with a link to "Return To Merchant".

Any ideas why this is not working?

By the way, the test purchase was used using the guest checkout/credit card link on Palpal's payment screen.
