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.
You're more than welcome to submit a pull request so the plugin takes into account you deleting UID1. Until then, being ungrateful about someone giving up more than 96 hours of their time making a plugin others can benefit from seems a little shallow.
Your issues may have spanned from the plugin being old/out of date. This is an issue when making plugins during a forums infancy, as development goes on, changes need to be made. But again, pull requests can be made to combat this.
