We have noticed that there is no problem with the integrating between our site and Paypal technically.
Every day we receive many purchases which are processed correctly through PayPal, so these errors are punctual, sporadic.
We contacted Paypal support, and they tell us that the problem could be momentary connection error, or some restriction for security reasons, currency or location.
The solution is:
- To buy using the other option available, through your credit card directly. It works well all the time.
- We can send you a payment request via Paypal directly. Just contact us at firstname.lastname@example.org by saying which products you want to buy. And we'll send you a charge by email. (It can take some time because we do it manually). Once the payment is confirmed you will receive a coupon code to finalize the purchase.
We are sorry about this issue and will continue to investigate what's the root of it it and solve it.
