I am trying to log in as admin with my admin Password and I error message "Unable to establish session: There is another Session under such name."

This means admin (or someone who has the admin password) is already logged in. Find the other session and log out or restart the control panel)

1. Log in to your server using SSH as root

2. On FreeBSD type /usr/local/etc/rc.d/psa.sh stop

3. On FreeBSD type /usr/local/etc/rc.d/psa.sh start

4. Try it again. It should work now.

If you still have problems after doing this then contact our support team for help with this by opening a trouble ticket.
