After moving to the latest snapshot (#1545), I cannot access HABPanel in my installation. All other user interfaces (Paper, Basic) and all bindings work fine. I did clear the cache and restarted openHAB. The console shows that HABPanel is active:
271 │ Active │ 80 │ 188.8.131.52903021856 │ HABPanel user interface
Did I miss any relevant change that happened from 2.4 to 2.5?
