Hi,
Please edit the file "components/com_hikashop/views/cart/view.html.php and change the code around line 314
By:
else {
if(empty($user)) $user = new stdClass();
$user->id = 0;
}
This modification would be include in the next HikaShop package.
HikaShop use a lot of "classname" on his HTML elements in order to help you to make some CSS customization.

If you want to add html content, you have to know that you can override all HikaShop views. In the backend, you can go into "Display > Views".
You would find all views and you would be able to edit a specific view for a specific template.
What page did you try to open to have the "please login first" message ?
We need to know the url in order to know the action you try to do.
Regards,
