I just set up a new Discourse install. While I was configuring my categories, I thought I wasn’t going to want uncategorized topics, so I deleted the category “uncategorized”.
Now I’ve decided that I do want to allow uncategorized topics after all. I have
allow_uncategorized_topics checked, but I don’t have a category named “uncategorized”. When I create a topic, I can give it “(no category)”.
I can then edit a “(no category)” topic and give it a category.
If I edit a categorized topic and set it to “(no category)”, it doesn’t remove the category. It appears to, but if I go back to the topic list, the category’s still there. If I return to the topic, the category is in fact back.
Did I work myself into a bad state? Should “uncategorized” not have been deletable?
