@juan-g If I’m not wrong this is only for groups. Anybody can't make subforum both with his own group.
This is interesting idea for plugin or like a feature for new version of core nodebb.
Good for wide community forums on autopilot, when owner not have enough time to support all desires of members.
I know this is quite old, but i encountered the same problem. I had localhost written in my config.json, but changed it to my domain. I still get GET http://localhost:4567/plugins/nodebb-plugin-emoji-extended/images/smile.png net::ERR_CONNECTION_REFUSED
I also restarted my server with the admin gui - is a hard restart or reinstallation necessary for the changes to take effect?
