Thanks Mike. No, I've paid with credit card and all is ok into Paypal. Make payment perfectly. But when return from Paypal to my web site, display: Error. There was a problem processing your payment. Please try again. show less

OK thanks. But I have tried in real mode and does not work. I pay correctly, but when you return to the web page always displays the following error:
"Error. There was a problem processing your payment. Please try again."
I access to Paypal account and the payment is ok. but on my web site always display this error and not add points.
Thanks show less
