I have been selling ebooks via paypal on my site for years, but it's not working now
I recently uploaded new ebooks on my site but customers have informed me the paypal won't let them pay. So I created a new paypal button and it's not working either. I'm still using the same paypal account email address as always but when you go to checkout, even if you choose to pay by credit card instead of paypal, after you enter your card numbers and billing address, the next page says there's an error, it's not working at the moment. Please advise.
