For some reason the header (as well as both the left-bar & right-bar) are not showing up in the cart once you have added a product to the cart.

Everything appears as you would expect when there is no products in the cart, but as soon as products are added (as stated above) the header, etc disappear. This happens whether the user is logged into the system or not.
I am currently using the vivid dreams - violet theme in X-Cart 4.4.5. I checked the demo online and it would seems as this is normal for this particular theme.
Is anyone able to tell me how to get the header (and perhaps the left & right bars) to appear in the cart whether there are products loaded in the cart or not. I assume I need to add some type of "include" statement into somewhere but I'm not sure where...
I would appreciate any help or suggestions. Many thanks in advance.
