When a new user registers on the site their information is submitted and saved , they add a product and when I try to buy their item, paypal screen comes up and say invalid transaction.
To fix this. I have to go under their name and go to /settings. Hit the save button , now everything works. It seems like the information is not saving to their settings page. Even though the information is filled in you must sign in as them go under their profile and hit save for it to work properly.
