- Plesk for Windows
SymptomsI cannot login to Control Panel as administrator, getting " Unable to login. There is another user with the same login (admin) already logged in to the Control Panel." error.
CauseThe reason of the error message is that the previous administrator’s session wasn’t logged off.
All the session can be closed using the Plesk Tray Monitor utility available from the operating system taskbar’s system tray by hitting the Delete Sessions button.
