### CSRF_TRUSTED_ORIGINS

This now needs to be set if you are proxying to your WSGI process, which is 99% of the time.

The easiest thing to do is to duplicate your `ALLOWED_HOSTS` setting in `settings.py` with something
like:

```
CSRF_TRUSTED_ORIGINS = [f"https://{host}" for host in ALLOWED_HOSTS]
```
