Hello,
I installed Discourse a few weeks ago for an association. The whole works well overall.
I am an administrator and I have appointed other administrators and moderators. Another administrator created a category and subsequently renamed it.
We want to edit the category, give it another name or delete it, but I get a 404 error every time.
I launched a ./launcher rebuild app without success.
Do you have an idea ?
Thanks,
Aymeric

Did they rename `uncategorized`?

No, it’s different name.
I saw somewhere a method to delete a subject from the server directly in SSH, could a similar method apply for categories?

I still think it’s uncategorized that now has a different name.
But yes you can do something like
```
Category.find_by(name: "ffd").destroy!
```

I’m guessing some accent in the slug, I had to
`./launcher enter app`
then
`rails c`
and
`c = Category.find_by(id: 'the_id')`
(q)
`c.update(slug: 'new-slug')`
exit and exit
Modify Category page was then accessible

🤔 what is your `slug generation method` setting ?

It’s automatic when you assign a name on new category. I think he created category with “slug” name “pour améliorer la communication du site des adhérents du CA” and he rename after “communication vélivélo”.

I mean the parameter, it could be set to `ascii` or `encoded` (then something might not work, but I’m not really sure of the expected results and consequences of either one 😅)

I do not know at all. I don’t know where the parameter is. I was thinking of using UTF8.

It is there:
`your.domain/admin/site_settings/category/all_results?filter=slug`

Hi, it’s ASCII. I never modify this.

Try setting it to `encoded` and see if that allows you to edit the category.
