The shopping cart will not update if Im not logged in after upgrade.

[Cosmicglenn]

I have Joomla 2.5 and Virtue mart 3.0.12 with comunitybuilder 4.0.1

The shopping cart will only update if I'm logged in. The shopping cart will not update if Im not logged in. Before updating 

VirtueMart 2.0 to VirtueMart 3.0.12 my customers could add items to cart and checkout with out being a member of my site or logged in.

Is there a way to fix this. They can check out without being logged in but they can not add items to cart.

Can anyone help?
