Trouble with accessing Headphones

I'm having trouble connecting to Headphones, which I have only recently installed again, and I think it is down to this commit, which is now covered on the Web Interface section of their wiki

For security reasons, Headphones will serve on localhost by default. This means you cannot access Headphones from another computer unless you change host to 0.0.0.0.

I've tried adding the following line into config.py in /opt/headphones/headphones, so it looks like so:

'HTTP_HOST': (str, 'General', 'localhost'),
'HTTP_HOST': (str, 'General', '0.0.0.0'),

And also removing the locahost option:

'HTTP_HOST': (str, 'General', '0.0.0.0'),

However I still cannot open the page after restarting the Headphones service after each of these changes.

Is there another process I need to restart, or any other changes that I need to make?

Sorted. Had to clear my cookies as well before it worked though. Thanks!
