Cart is empty after I activated the account via link in the email

[nhan]

Hi All,

I am facing a problem as follows:

1. I added 2 items into the cart, then do the checkout.
2. I registered and was asked to activate the account via the mail.
3. When I clicked the link in the email, then the site (opened in the new tab) alerted  I activated the account successfully, but the cart is EMPTY.

VirtueMart 2.0.2
Joomla 2.5.7
Firefox 16.0.2

Is there anyone have a solution for it?

Thanks in advance.
