Hi, I'm having the same problem. A few weeks ago, I noticed that all the PayPal buttons on this page (http://www.highland-games.co.uk/Dodgy-Dice.php) of my website had stopped working. I'd created them several years ago. I replaced all the 'add to cart' buttons with new code and that fixed them. I then replaced the code for the 'view cart' buttons but they remained broken. I get directed to (https://www.paypal.com/cgi-bin/webscr) but see a blank white page. This is the code I am pasting from PayPal's 'create a view cart' button page: <form target="paypal" action="https://www.paypal.com/cgi-bin/webscr" method="post" > <input type="hidden" name="cmd" value="_cart"> <input type="hidden" name="business" value="XLZX9C9VJ82UG"> <input type="hidden" name="display" value="1"> <input type="image" src="https://www.paypalobjects.com/en_GB/i/btn/btn_viewcart_SM.gif" border="0" name="submit" alt="PayPal – The safer, easier way to pay online."> <img alt="" border="0" src="https://www.paypalobjects.com/en_GB/i/scr/pixel.gif" width="1" height="1"> </form> As far as I can tell, the code is essentially the same as the unencrypted example earlier in this thread. I presume the problem has come about due to some change in PayPal's encryption methods, because one day the buttons worked, then the next they didn't work in any browser. I'm totally at a loss as to what to do next. I'd be very grateful for any help.
