I can't make the login form show up for users that are not logged in.
I see this:
echo shopFunctionsF::getLoginForm ($this->cart, FALSE);
on line 79 of the default.php file in the cart view but it doesn't show up.
How can I make the login form show up?
VirtueMart uses Joomla's login, so you can use that login module, and use a redirect plugin if necessary - http://extensions.joomla.org/extensions/extension-specific/virtuemart-extensions/virtuemart-administration/11109
