Hello,

I have run into an issue after the latest update `3.3.0.beta1-dev`. The update ran without a hitch and everything looks OK - as long as you are logged in.

For anonymous users the start page looks fine. But there is an issue loading a topics body - you can see the title, the scrollbar is there to scroll through all the posts, but the text is not beeing loaded:

The error message I can see in my Browser console is:

> **Chrome** :  
> `retort.js:48 Uncaught TypeError: Cannot read properties of undefined (reading 'postStream')`

> Firefox  
> `Uncaught (in promise) TypeError: this.model is undefined`

Complete trace:

Can someone point me in a direction on how to fix this issue?
