UI's not loading properly


I’ve just setup my.openhab and can see it’s connected to openhab correctly, my items and events show up instantly.

When I try and go to my dashboard from my.openhab, the dashboard loads but when I click any of the UI’s none of them load properly.

E.g. When I try to load habmin, I just get a blank page which says “Loading…” and never actually loads.

If I try and load PaperUI, I get this screen and none of the links in it actually do anything:

Is this supposed to work properly with habmin and paperui or is it more for sitemaps in basic or classic UI’s?
