Is/has any one else gotten this error message after selecting the "PayNow" button from PayPal ? I get this error after I check out of my prestashop cart pass over to Paypal, and login using my Paypal account. A few things I am using Paypal v 1.4 presta 1.1 and have confirmed the site is working with paypal correctly through the Paypal Sandbox. Googling the error I saw potential solution on the paypal developer boards. Per that solutions I have tried to change the following line in paypal.tpl from this
<form action="{$paypalUrl}" method="post" id="paypal_form" class="hidden">
to this
<form action="{$paypalUrl}" method="post" target="paypal" id="paypal_form" class="hidden">
No success Then I called paypal... and the rep suggested that I the following line from paypal.tpl
<input type="hidden" name="upload" value="1" />
<-- I figured this was not going to work, and indeed, No success! as obviously now the cart does not know what to do with the data its receiving I tried to replace the above code to this
<input type="hidden" name="add" value="1" />
and this does not seem to pass all the information to the paypal cart either. ( I also had another person try to process their credit only with Paypal and they received a message I also got which was that the card could not be process.) Called back paypal and they tell me I need to talk to the merchant technical support line. I will call but wanted to know if anyone had experience solving this issue or has any advice. Thanks in advance for help Suz
