We have recently moved the following magento website to our server space [login to view URL]
But we can't get Paypal Express working on it. When you click on checkout with Paypal it goes to paypal as expected and comes back to [login to view URL] on the site as expected but when you click 'Place order' it comes up with the following message - There was an error processing your order. Please contact us or try again later.
The exception log is showing
