When I have the paypal settings in PPV set to Live, I can click through and get a paypal express checkout page (I don't want to complete the purchase in live mode). When I change "Live" to "Sandbox" I get the following error:
There was a problem connecting to PayPal to setup your purchase. Please try again.
10002 – Security error – Security header is not valid
Do I need separate credentials when in Sandbox mode? If so, it's not clear within the plugin. I want to be able to execute the entire purchase in sandbox mode so I can verify that when I return to the page I can view the video course and other page content.
Also the link to "instructions" for getting API credentials leads to a page that no longer tells you how to do this (when I installed the plugin, this worked, and I had my client follow the instructions and send me the resulting info). I think Paypal changed things in the last month or so. So the documentation within the plugin is a little out of date.
