After a buyer has purchased via PayPal a "Return to Merchant" link is provided that usually leads to the buyer's E-junkie generated thank you page where they can review order details and download their digital products.
For many orders it appears that this link is currently stepping back to the original sales page instead, but our system is still processing the orders and delivering email messages with the buyer's download information and links otherwise.
We have reported this issue to PayPal, as it appears to be a problem on their end.
