Virtuemart cart problem

Hi

I configured the virtuemart, but I have a problem. If I put an item in to the cart and I click the cart button in the pop-up window, I can check out. But if I click on the cart button on the right top corner, sometimes say ther is no items in the cart or I has the selected items but I can't checkout.
There is an other problem as well both case. If I try to cancel an item or change the quantity I can't. Could you check it on this page: www.albakupon.hu

It is a test domain so you can do anything.

everything is ok, what browser do you use?

I'm using chrome but I tried with firefox and the problem is the same. Try to put something in the cart and after that click on the cart icon on top right corner. You will see what is in your cart but if you click the "Pénztár" cashout button you will get a blank page with an error message. Or try to cancell or change the quantity, you will get an error message as well.

Check if links in virtuemart.cfg.php have "www." or not . Try both cases . There is that setting in two places and it must begin the same way.

Also try this:

dense13.com/blog/2008/02/27/redirecting-...o-www-with-htaccess/

I can't find in this file where should I put this 'www.' prefix. Could you be more prcise?
If I click the cart button on the pop up window and after that the cashout button the link look like this: www.albakupon.hu/index.php?page=checkout .....
But if I click the cart button on the top right corner and after that the cashout button the link what is missing looks like this:
www.albakupon.hu/nails?page=checkout ....
The difference is the "nails?" instead of the "index.php".
Why they are not the same?

file where you shoud check links is:

administrator\components\com_virtuemart\virtuemart.cfg.php

lines to check:

P.S. values should be like this.
