I have been using Paypa's "Add to Cart" buttons for many years. In the generated button code, the form target="Paypal" is replaced by form target="_self" in order to let Paypal's "Continue Shopping" button to return to the webpage on which the "Add to Cart" button was last clicked. It used to work perfectly for years. However, in recent months, the "Continue Shopping" button leads to our website's homepage instead. Any help is much appreciated.
