We followed the paypal tutorial to the letter and published the site.

Everything was absolutely fine with paypal until we got to "Return To Merchant", but when we hit the button to send the buyer to a download page it kept sending us to "Web Page Cannot be found".

We manually typed the URL we had assigned to the paypal button into the browser, and it took us straight to the page.

We've taken the site down, just in case we have purchasers overnight, but can publish again tomorrow if someone can have a look at what's going wrong.

Really appreciate any help we can get
