I can't get my site to connect to PayPal either sandbox or live. I've double checked my API credentials, I've double checked my sandbox credentials. I'm trying to set up a multi-cart environment and my test is on the main site - http://www.artisanjewelrymarket.com
I get the following error while set to sandbox:
There was a problem connecting to PayPal to setup your purchase. Please try again.
520009 - Account email@example.com is restricted
My sandbox email is firstname.lastname@example.org and that's the email I used for my (many many) tests.
I have disabled all plug-ins except Marketpress and wpmu dashboard. Does anyone know what that error code means or what I can do to make it work? I'd like to get the sandbox working first and then tackle the live test.
