My website sells things through a simple HTML form which posts to action="https://www.paypal.com/cgi-bin/webscr".
Among the inputs, there's input type="hidden" name="business" value="some email address".
Until recently, every sale was notified by email to the specified e-mail address. Since December, the notifications have been going to a different e-mail address. I haven't made any change to the website. How can I restore the original behaviour?
Extra information: the purchaser naturally gets an e-mail confirming the sale. That includes the statement "payment sent to <wrong e-mail address>". However, PayPal gives me (as the seller) a record of the transaction, and that says "payment sent to <right e-mail address>".
