paypal error

Hi

We are getting aPaypal error:
"This merchant requires us to use the shipping address you entered on the merchant site, and there’s a problem with that address. Please go back to the site to change the address"

There is no problem with the address .
Can someone help please

Thanks
Jonathan

I'm not sure which version you are using, but in about 3.50, an update was made to this plugin which includes a new checkbox in the configuration:
Address override:

You must check this box, or else if the address the customer has in their nopCommerce account doesn't match the address they have configured at Paypal EXACTLY, it will be rejected.
