Hi @neso, the `Discourse._registerPluginScriptDefinition is not a function` error was fixed in [Revert plugin js changes (#5139) · discourse/discourse@7d350d0 · GitHub](https://github.com/discourse/discourse/commit/7d350d0d75f024e6817d15f1dfafcf391a061331) last week.

In order to access the admin/upgrade page again, you’ll need to SSH into your server and run

```plaintext
cd /var/discourse
./launcher rebuild app

```

Here’s the topic from last week:
