If you change version on `app.yml` from `tests-passed` to `stable` it will give you the latest stable on a rebuild. Currently 1.6.x is our stable version.

doing this change in app.yml file, I got the following error:
```plaintext

Can you paste the entire logs?
Also, this is a brand new discourse right? You can’t go back in Discourse, so if this was an existing install of 1.7.x it won’t work.

yes, we were on the latest version, and we ran into some problem that looks like [this](https://meta.discourse.org/t/site-goes-blank-if-you-override-translation-for-js-groups-index-title/54732) thread, with the difference that it happens for the string `js.user_action_groups.1`.
I’d be thankful if you let me know:
1. can we downgrade to some version before?
- is it a bug about the strings or is it something related to our forum?
- is there any way to come out of this state? the forum is even blank in the safe-mode. and I think there should be some thing related to the source code. that’s why we think of going to older version.
we can’t restore the beckup on local, and I’m afraid if the backup is broken. So I don’t dare to drop the database. + not sure if that’s the solution ☹
p.s.: sorry can’t put the whole log in the right way.
**update** : it got fixed out of no-where! no edit in the `app` file except some trials to go to older versions and then to newest version after it didn’t work!
