Menu don't shows at cart page

Hi.
I'm trying to figure out why the site menu don't shows at the cart site.
I know I can able and disable menu and modules at menus and modules, but when I go to the cart page all the menu an top menu disappears.
Is this a Joomla issue or a Virtuemart issue?

You probably need to add a Joomla menu item for the shopping cart - you can make it hidden if you don't want to display it. Then add that menu item in your modules.
