Sorry, I may be repeating a previous question. I see one in the in the list of the forum, but reading it, it does not sound like my problem.

I have installed 1.5.0, it is an upgrade from 1.3.0. The upgrade was done by installing 1.5.0, then reloading the database. The site has template differences from the standard, but, the engine of zen cart in not modified, with the exception of the pulugins:
- newsletter subscribe 2.2.2
- sales report
- ultimate seo url 2.150

When I use paypal to pay for products, I return to the Payment Information Page (2 of 3) and get:

"Error PROBLEM: We're sorry. PayPal has unexpectedly returned a blank address.

Then you may select PayPal again when you continue with checkout. We apologize for the inconvenience.

Can you point me in the right direction to solve this problem?

Thanks for your time.
