Can not enable project

I followed your guid in the Readme.md file and after starting the server, I'm able to see my projects. But when I click on the enable button nothing happens. Output from npm start on the commanlind:

```
GET /stylesheets/style.css 304 1.647 ms - -
GET /projects/37/enable 302 264.973 ms - 58
```

Any ideas how to start debugging? Also I can not see any Deploy Keys or Wehooks for the project I enabled, do they have to appear "normal" in the project settings view?
I'm using a selfhosted gitlab server if that matters.

Thanks for helping,
Flo
