I've bought several things off Aliexpress over the years but now I am having a problem. I am trying to pay using my usual credit card, but this time it keeps saying:

"payment failed system currently unavailable"

I tried several cards with the same result. Looking on the AliExpress forum shows this has been going on for some time for Visa cards with no solution. I've emailed the seller (Fred) to let him know I'm having problems - any one come across this recently?

Thanks
