The Paypal interface seems to have stopped working and I have no idea why. At first it only seemed to be customers from outside Canada that couldn't complete payment but now it is all orders. I tried it myself and it just hangs at the Paypal pop up screen. When this is closed there is a small box behind it that says "Error in ajax posterror", whatever that is (see attached screenshots). I tried uninstalling and re-installing the Paypal module but this had no effect.
I've lost loads of orders due to this issue so I need to get it working asap. Can anyone help please?
Thank you.
