Something in the AI plugin has broken the Discourse app: I realised that **all topic are not deletable** (500 Internal Server Error).  
In the admin panel of AI plugin, the tab “LLM”, “Personas” and “Tools” are disappeared, so I cannot delete my LLM model.  
I have removed the automation related to the toxic topics, disabled the AI plugin, disabled the Automation plugin, but the problem still persists.  
Then I deleted the AI plugin row from app.yml and destroyed/rebuilded/started the app, but the problem still persists.  
We took a look in the postgres db and there are still some tables about AI plugin.

Here are some details about 500 error when we try to delete topic or post:

Hey @Alessandra_Casale / @ecesarini,

This behavior is quite uncommon, and as it persists after removing a plugin, it is not caused by it.

Can you share more details about how did you install Discourse? What version are you running? This errors are still happening after a rebuild?

From the logs it appears that the installation is corrupted and missing files, so we need more information to help you.

Hi,  
thank for your help.

- Discourse is deployed via docker, using a configuration file based on **standalone.yml** sample you can find in the official repo discourse\_docker repo. We just set the required fields and the list of plgins to install. The instance has been running for several months and this kind of problem has never happened before the configuration and activation of AI plugin
- Discourse version/image tag is **v3.3.2**
- Yes, we have destroyed and rebuilt instance several times but the 500 error persists when admins try to delete any post or topic in the web interface. Errors don’t occur deleting elements via cli in rails console (e.g. `Post.find(<#ID>).destroy`)

If we try to edit or move post/topic everything works fine.

Here’s the plugin list if it could be useful

```-
          - git clone https://github.com/discourse/discourse-oauth2-basic.git
          - git clone https://github.com/discourse/discourse-openid-connect.git
          - git clone https://github.com/discourse/discourse-saml.git

          #- git clone https://github.com/discourse/discourse-jira.git

          - git clone https://github.com/discourse/discourse-topic-voting.git
          - git clone https://github.com/discourse/discourse-assign.git
          - git clone https://github.com/discourse/discourse-templates.git
          - git clone https://github.com/discourse/discourse-translator.git
          - git clone https://github.com/discourse/discourse-gamification.git

```

In the last rebuild **ai** and **jira** are commented out but those errors are still happening
