Paypal not working
In order to use Paypal, the funding source attached to Paypal must allow international transactions. If your payment fails, it won't usually be Paypal, but the funding source attached to Paypal.
If the Paypal button doesn't appear to work at all or is missing entirely from the page, then you're likely using a 'safe browsing' page provided by various anti-virus tools. If you're asked whether to open our shop in a safe-browsing window, always click NO. If you're no longer being prompted but you believe the page IS opening in a safe-window, take a look at your anti-virus/internet security app's settings where you should be able to remove us from the list of sites to be opened in a safe window.
