Checkout Problem

Hi,

We are using PayPal hosted for both PayPal & credit/debit card payments on our website https://www.lovemygifts.co.uk

We are noticing a number of problems reported by our customers & our own testing is showing the following issues.

? When checking out via card there is no screen to show payment processing after hitting the orange Pay Now button. You hit the button & the screen is just static.
? This has meant customers are hitting the button more than once resulting in double payments
? Customers are not receiving payment confirmation emails in inbox or spam (tests in house are showing the same problem with no emails being received)

Should there be a payment processing screen as standard. Or can we create one?

Please advise, many thanks.
