As the translations are mostly done by the community, errors will likely occur. I only handle the Dutch language so I can't do much about it. But it might be for the best if it is reported somewhere for the translators to fix them
Pulling from Master helped. However the webpage that starts NodeBB after setting up the DB through the webpage, doesn't restart it now. I had to kill the command line, and manually start nodeBB. But then it works fine. Just an FYI.
I installed the wrong software stack. I installed the one in the ubuntu installation and i notice the one in the actual mongo db installation is different, once i installed that one, my login panel appeared. Thanks for the help everyone.
