> How can I back out of this update

If you’re using the Docker deployment method, you may have an older container which you can restart (check e.g. `docker images` and/or `docker ps -a`).

You can also override the commit used to build the Discourse instance by editing `app.yml` and setting the version to the commit prior to the change, then rebuilding:

```plaintext
params:
  version: adb7fa5e2fc51308efc9fc4ee57ecb1c15a85cfa

```

Discourse will break again if you update after this, which is not ideal given the [security update](https://meta.discourse.org/t/2-9-0-beta7-security-fix-bug-fixes-and-more/232721) that has been released since (although exploitation potential seems pretty limited for most instances).
