When I go into the "Edit Your Products" tab there labeled "Product URL Please enter URL, relative to Site root ex.: /mydir/protected_dir1/" what does this mean and where can I find the site root? Help much appreciated, thanks.
If your site is http://www.yoursite.com/ then http://www.yoursite.com/ is your website root. For example, if you protect folder http://www.yoursite.com/members/, you must enter /members/ as value for "Product URL" field.
