I installed the Paid-Download on my wordpress pade ... http://www.aspadas.aspadas-tec.de/parkjet-f22/ ... if the user push the button the sandbox open ... but he can not login with his password and login. He have to open an Test PayPal account but can't pay in his usual way.
Whats the problem?
Is there a difference between PayPal USA and German Accounts?
Thanks for your help ;-)
