i'm testing the PP Express Checkout contrib (5687) v.2.20 and have the following problem: After paying with PP the user is redirected to osc-url/catalog/ppeb.php?geppec=1&cusid=102&addid=79401&fn=TEST&cou=81&zonid=0&payid=D8ADBHOKQK34&tok=EC-098790870987A&Amt=&cur=&payt=&shec=A
and shows the error
select customers_default_address_id from customers where customers_id =
The order is not placed but the customer is created.
I think the problem is the url as there are html special chars in. Does anyone know wether this is a Paypal problem or a bug of this contrib (how to fix it?)?
