Publisher review:Back Button Improved solves the problems associated with 'force cookies' as well as having no history to go to, therefore a '401' is given. As you may see, the fix is simple and 'old school', but it works. This is the only fix I could make that did not include heavy editing.
Always keep a backup of all files you are working with. Maybe even use a test site instead.
