AddToCart doesnt work

After you hit Add To Cart Button, it shows only a blank page. Here is a link to the website: www.temay.net/index.php?option=com_hikas...y_pathway=12&lang=en

I just tried and didn't get a blank page.
Though, I noticed that the redirection URL contained & instead of &. Maybe that could be related. To fix that you need to have the version 1.3.5 and change the file components/com_hikashop/views/product/view.html.php and change the code to near line 690

done that and still getting a blank page on add to cart.

errr. it works on IE. maybe i need to clean my cookies on Mozilla. Now, the my account/My cart is not displayed anywhere.

It works on all the browsers I tried...Probably a problem of cookies/session/cache or something.

How can I add "My account"&"My Cart" Menu?

Go to the joomla menu manager and add a menu of type HikaShop. There you can select the user cpanel layout for My Account or the checkout layout for the My cart menu.

Thank you very much.
