When logged in to my account at my site I don't see Previous Orders under My Account. I don't have a "view" button at all. I have made purchases so I should see my order history.

Also my gift certificate balance vanished from my shopping cart.

Both the previous orders and the gift certificate balance were working a few months ago when I last logged into my site. I haven't got any addons.

I am using v1.3.9h

I don't have a clue where to start looking to fix both problems.

Can anyone help me?
