Cherie,
A HTTP Error 401 – Means “Unauthorized” That is, the user/browser doesn’t have the correct permissions or isn’t logged in to view the page.
Generally this error message means you need to log on (enter a valid user ID and password) somewhere first. If you have just entered these and then immediately see a 401 error, it means that one or both of your user ID and password were invalid for whatever reason (entered incorrectly, user ID suspended etc.).
This can also be caused by screwing up something in your .htaccess files. If you have cPanel, you can add custom error pages without ever having to mess with your .htaccess. If you restore your .htaccess, does the problem go away?
