Expected Behaviour:
I should be able to go to the admin interface via pi.hole/admin or directly via 192.168.178.48 (the static IP).
Actual Behaviour:
Cannot load the admin interface via either of the methods (ip or pi.hole/admin, lighttpd service does not start and even taking ownership of the /var/log/lighttpd folder and files within does not fix the problem as suggested in other threads: Pi-hole no web interface access and lighttpd.service failed to start
