Steps to reproduce

1. Use the stable30 version of juliusknorr/nextcloud-docker-dev. I set up fresh containers so it is in clean state.
2. Install files_downloadlimit app.
3. Go to "Sharing" in "Administration settings".

Expected behaviour

Successfully render the settings page as in Nextcloud AiO deployments.

Actual behaviour
