We have the same issue; PayPal is notifying us about updating our PayPal buttons but seem to be working OK and re-directing to the new page. Could you please help? We are using PHP Toolkit for PayPal and the following code: <form action="<?php echo $paypal['url']; ?>" method="post" name="frmPaypal" id="frmPaypal"> <input type="hidden" name="amount" value="<?php echo $paypal['amount']; ?>"> <input type="hidden" name="invoice" value="<?php echo $paypal['invoice']; ?>"> <input type="hidden" name="item_name" value="<?php echo $paypal['item_name']; ?>"> <input type="hidden" name="business" value="<?php echo $paypal['business']; ?>"> <input type="hidden" name="cmd" value="<?php echo $paypal['cmd']; ?>"> <input type="hidden" name="return" value="<?php echo $paypal['site_url'] . $paypal['success_url']; ?>"> <input type="hidden" name="cancel_return" value="<?php echo $paypal['site_url'] . $paypal['cancel_url']; ?>"> <input type="hidden" name="notify_url" value="<?php echo $paypal['site_url'] . $paypal['notify_url']; ?>"> <input type="hidden" name="rm" value="<?php echo $paypal['return_method']; ?>"> <input type="hidden" name="currency_code" value="<?php echo $paypal['currency_code']; ?>"> <input type="hidden" name="lc" value="<?php echo $paypal['lc']; ?>"> <input type="hidden" name="bn" value="<?php echo $paypal['bn']; ?>"> <input type="hidden" name="no_shipping" value="<?php echo $paypal['display_shipping_address']; ?>"> </form> Thanks in advance.
