Plesk 7.5.4 Web Stats Issues

I have noticed that when I first create a new domain on my server and choose to provide that domain with "Web Stats" all of the ftp passwords and user names are assigned to the "Web Stats" access page. While that is fine by me and works great, I have noticed something that does not work. Updating passwords on FTP accounts doesn't seem to carry over to the Web Stats access pages. Basically if I started off with a user name and password of: user123 pass123 Then change to: user543 pass543 It doesnt work with "Web Stats" and I can still access "Web Stats" using the old info that I originally setup. Even if I restart Apache it doesn't help. Does any one know why this would be happening or if there is something that I am missing? Thanks in Advance! Max $30.00
