we tried a paypal payment in live enviroment. The payment is succesfully received in paypal, but the IPN status is unconfirmed in my paypal dashboard. (it's a business vierified account). So Pledge is not recorded.
We activate the ipn and insert http://clon.partidodelfuturo.net/wp-admin/admin-ajax.php?action=wdf-ipn-return-paypal as the return url.
So, don't really know where is the mistake.
Thank you for your support
