I manage a Discourse instance on [https://lilypond.community](https://lilypond.community). A few hours ago, I used the Web interface to upgrade Discourse to 3.3.0beta2. It failed with the same error as on [3.3.0.beta2-dev update error - #8 by david](https://meta.discourse.org/t/3-3-0-beta2-dev-update-error/308163/8). At that moment, I didn’t have the time to investigate, so I left it as-is, but the forum still looked functional. Now it’s giving

on any page (`/`, `/t/topic-slug`, etc).

I followed the advice on the linked topic:

```plaintext
cd /var/discourse
git pull
./launcher rebuild app
./launcher start app

```

but it didn’t help. I’m not 100% sure the problem is actually related to the upgrade, though I find it likely.

This is what I find in `/var/discourse/shared/standalone/log/rails/production.log`, just after trying to access the page `https://lilypond.community/t/effacer-les-citations-du-conducteur/5698/8`:
