Ignore previous commit, this should fix it properly https://github.com/NodeBB/NodeBB/commit/071506eb7dc99e057b5bfde4543eadb75174a19a 👼
Fixed on master
After doing some other stuff like resetting themes and reloading, restarting, it seems to be working now. I wonder if it's related to this, which also happened: https://community.nodebb.org/topic/4129/new-topic-no-display-nodebb-0-7-0-ubuntu-14-10
And lol I forgot to install Persona. Whoops.
I've tried to load my forum with port 8000 (http://*.rhcloud.com:8000) and then in category permissions groups are shown properly. I'll use http://myhost.rhcloud.com:8000 when want to set category permissions.
The unread page works well if the # of new posts per visit is fewer than 10. After that it gets a bit hard to keep up 🙂
Some newer changes may make the list a little more manageable.
