Please enter the user name and password and the path of the directory you want to protect.
The path should look like something like this /usr/home/website
Or perhaps something like this /ux47/0/154/public_html
Just remember it has to be the absolute path.
I have found out that some servers do not show you the absolute path in your ftp program,
so you may have to ask your hosting company what your absolute path is.
