New blog PayPal sandbox redirect after payment is a 404 page

Hi All,

Running WP 4.5.2 Multisite with Pro Sites 3.5.4

I am testing PayPal integration in Sandbox mode. I have a couple of issues that I have been banging my head against for a while now. :slight_smile:

1) When a test end-user registers after successfully completing the PayPal payment page (using a Sandbox buyer account) the redirect page is a 404.

The redirect URL is: site_URL&action=complete&token=EC-8GA162862D113681B&PayerID=PGJ594EAX77F8

The transaction does not show up in PayPal Sandbox.

2) The Pro Sites documentation states:

enter your IPN url (http://site_URL/wp-admin/admin-ajax.php?action=psts_pypl_ipn) in your PayPal profile (you must also do this in your sandbox account when testing).

I don’t see anyplace in Paypal Sandbox accounts to enter this URL. I do see where it goes in the Live account.

This setting missing actually might be why the redirect is not working?
