Keeps redirecting to Cart after succesful purchase

I have installed this on a test environment, whenever I buy something, the user is redirected to the shopping cart (which is now empty). This can potentially confuse users.

I requested direct support through your website about 5 working days ago and was contacted to ask which version of the plugin I was running, which one would assume “Latest” would be the answer a support agent would think.

PayPal is working absolutely fine in our site, and we’ll have to go with them if this issue cannot be resolved in a prompt manner.
