I'm having problems also, the actual installation seemed to work fine but I there now seem to be several problems.
Customers can't login, they're just returned to the welcome guest screen.
The default currency wont seem to stick with ? anymore, just constantly to dollars.
When clicking on an item to add to the cart it just says 'Your cart is empty!'.
Url to the site is http://gnome.i-rox.com
Any help greatly appreciated.
regards,
Tim.
