I had no cgi-bin navigation errors even from the www.home page (now there is a mention of www - it's the home link on the top menu - which means the bottommost setting on the network setup page - usually).
I added to cart, progressed to page 2 of checkout and came back to view cart to remove my items (I had to look for the buttons - and only did because I knew they should be somewhere on the page - they really should be directly under the cart).
EDIT: Found & Fixed that bit - ta fer pointing it out!
