Can't add items to cart
Site:
When I click to add item to cart, my personal name above the shopping cart icon disappears and it asks me to re-enter account information. If I click shopping cart icon, or click back page - my account name appears again. But repeatedly, from different pages - when I enter an item in search, find item, and attempt to add to cart - account name disappears and I am again requested to enter account information.
