Just checking - have you seen this?

>
> ## Updates for self-hosters
> 
> For self-hosters using this plugin, our most recent update would require a manual rebuild of the index. This would involve running this rake task:
> 
> ```plaintext
> bundle exec rake doc_categories:build_sidebar
> 
> # if running the task above fails due to NoDatabaseError,
> # run with the following for typical self-hosted setups
> sudo -E -u discourse bundle exec rake doc_categories:build_sidebar
> 
> ```
> 
> If you are not able to run this rake task, **you may go to each documentation category’s settings, remove the category index, save, add it back, and save.** This would rebuild them and refresh the category cache as well
