Submitting suggestions is broken

[RokkuCode]

Using the current stable Vivaldi (Chrome based Browser) throws an error:

Acess to fetch at 'https://backend.datenanfragen.de/suggest' from origin 'https://www.datenanfragen.de' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

Thanks for the report, @RokkuCode! This seems to have been a problem with our backend that should be fixed by https://github.com/datenanfragen/backend/pull/68.

The fix has now been merged and should have fixed this.
