Hallo Freunde,

meine Discourse-Installation ist nach dem Upgrade von 2.5.0-beta3 auf 2.8.0-beta1 kaputtgegangen.

Problem:

1. Ein Klick auf das Hamburger-Menü öffnet kein Menü.  
Daher kann ich keine Admin-Aufgaben starten.

2. Es gibt einen Fehler in der JS-Konsole (wird wiederholt angezeigt):

```plaintext
popper.js:25 Uncaught Error: There is no route named admin
    at RouteRecognizer.handlersFor (popper.js:25)
    at NamedTransitionIntent.applyToState (popper.js:25)

    at renderThunk (popper.js:25)
    at handleThunk (popper.js:25)
    at createElement (popper.js:25)
...

```

Habt ihr eine Idee, wie man das beheben kann?
