The PHP Live! system has few different login areas that you'll want to make note.
For example, if your PHP Live! URL is www.YourSite.com/phplive
Operator URL: http://www.YourSite.com/phplive
If an operator has forgotten their password, reset the password at the setup administrator area.
Setup administrator URL: http://www.YourSite.com/phplive/setup
If you have forgotten the setup area password, refer to the setup password reset documentation.
Windows WinApp URL: http://www.YourSite.com/phplive/winapp.php
