I have a single user set up in Tvheadend (*) which has permissions to basically watch TV but not access the web UI. I then use the superuser to login to the web UI. Recently I got annoyed with always having to login so I gave the * user permissions to view the UI but not change anything. Now, I see the web UI without logging in, but I can no longer login using the superuser account. I have tried adding "-C" to the "OPTIONS" parameter in /etc/default/tvheadend but it doesn't help.
How can I re-access the web UI without blitzing my entire installation?
It looks like this bug is related:
