2.0.7B - Cart ask to login even if logged

[hpolimar]

Hi,
i've upgraded from 2.0.6 to 2.0.7B. All went fine except that when i open the cart, in the top it asks me to logn even if i'm already logged in. But even if i put again name and password, the request to login stays there, even if i'm able to go on and complete the checkout. How can i fix it?

thanks
