You can add this after your hostname to your LiteSpeed server to access the admin section:
:7080/login.php for example: host.domain.com:7080/login.php
There, you'll see a login screen.
CPanel servers dot not show the Admin Password for LiteSpeed when set up, so you'll need to reset it with this command from root with an SSH tool or the terminal in cPanel:
sudo /usr/local/lsws/admin/misc/admpass.sh
The default username is: admin
