@lukelarris I run into the same issue in 14.04 server too. You need to install nodejs-legacy through apt and it's running well then 🙂
How can I login to ACP?
When I try to access to http://127.0.0.1:4567/admin on my local computer, the NodeBB asked me to login, what username/password should I use?
the user name and password of your user you created when you set up your NodeBB installation.
@Scuzz Thanks! I think I forgot my username and password, but I have re-install it
