Gettting error while making payment by paypal account

[vipin]

I am using Prestashop 1.3.1 for my website www.123dukan.com I configured paypal module for the site . when we unit test this it was routing correctly to paypal site but now it is giving following error .
Unable to process payment. Please contact the merchant as the shipping address provided by the merchant is invalid, and the merchant has requested that your order must be shipped to that address.
I followed up with Paypal and I got the following message from paypal
"Unfortunately there is not a setting within your PayPal account that will resolve this error response, it must be resolved through the code of the shopping cart on your site. This error means that the integration you are using has a variable ADDRESSOVERRIDE or address_override (depending upon you using PayPal standard or PayPal APIs) set, that it sends through the request data sent to PayPal at checkout.
In short what this variable presents means is that the address your shopping cart provides to PayPal must be the address used by the PayPal system and if this address is incorrectly formatted or if the country of the account being used for payment is different from the country sent by the cart in the address field you would get this error or a similar message to the one referenced.
To remedy this you would need access the code of the website that sends this data to PayPal, find the ADDRESSOVERRIDE or address_override variable within this code and edit the variable’s value from "1" to "0" or remove the variable altogether from the code string being produced by the shopping cart. "
I changed the address_override to 0 in redirect.tpl but I am getting the same problem . Please let me know the possible solution for the problem .
Thakyou

This would only occur for countries where mandatory information (state) is not supplied. I.e. Italy, China, Japan.
Strangely enough I've only seen this for Website Payments Standard implementations; which one are you using? It looks as if you're using PayPalAPI?
