BAD_INPUT_ERROR on transactions

[zark751]

Hi, all of a sudden our website https://www.asia-market.it stopped working with paypal (we use PayPal Pro since several years).

Without any change on our side, all payments done using a paypal account credit end up in a page like:

https://www.paypal.com/webapps/shoppingcart/error?flowlogging_id=81f4250d13580&code=BAD_INPUT_ERROR

And there's nothing we can do about it... All transactions fail!

Anyone knows what the problem could be? This has a devastating impact on the site and on the users' patience... Please help!

The steps are the following:

1. User clicks "Confirm order" in our site (https://www.asia-market.it/shop/checkout_confirmation.html)

The payment form is something like this:

<form role="form" name="checkout_confirmation" action="https://securepayments.paypal.com/cgi-bin/acquiringweb" method="post" id="checkout_confirmation"><input type="hidden" name="securityToken" value="ea97ccfddf3736a4045ef8ef563bee2e">

</form>

(I have ***ed emails and changed customer name for privacy). There are apostrophes in the customer's name and address but the issue happens also without

2. User is redirected to https://securepayments.paypal.com/cgi-bin/acquiringweb

where he's offered the choice to pay with Paypal or credit card. User chooses to pay with Paypal.

3. User is redirected to https://www.paypal.com/it/cgi-bin/webscr

Again, user chooses to pay with Paypal

4. Paypal requires the user to authenticate.

4. After authentication it goes back to https://www.paypal.com/it/cgi-bin/webscr?cmd=_flow&SESSION=0nSKGMvs_Vh55ybC8aMlAEjOQt7ooBRFh8zIHTgbB...

where finally there is a "Pay Now" button

5. Clicking the "pay now" button user is redirected to the error page

Thanks in advance
