New Post: Problem with Smooth Login

Hi Rob, I tried to understand your suggestions but I couldn't.
I don't know if my problem is the dnn version or the site folder, because a create a store in a child portal.
Could you help me?
The problem is on checkout the system always ask the login again and we can't finish the order.
