Error after install

After following the install guide, it gives me this when I try to view it.

URIError: http://192.168.1.5:8123/local/custom_ui/floorplan/lib/floorplan.js?_=1519050233960

Under frontend: what have you set the javascript to be I use latest but you can also use auto.

javascript_version: latest

Thanks, may have worked.
