I've installed the Paypal Pro plugin, following http://manual.amember.com/PayPal_Pro_Plugin_Configuration I'm probably missing something, and I'm getting crazy. When I fill the payment form (like a customer so), I'm systematically getting the following error : What the hell is going wrong right there ? What is the issue ? I do have a Paypal Pro API. I also do have a SSL certificate and I'm using a https:// address. Do I have something to do to "associate" the SSL certificate of my website to the Paypal Pro plugin ? I'm getting lost, please help...
