Cannot move sub-sub-category from UI

If I want to move a topic to a sub-sub category it does not work. moved it now via Commandline, but would really appreciate if you could change sth. on your end.

AFAIK tertiary categories are only supported with hosted customers, which is why you have you tinker with a hidden setting.

If this bug also affects hosted customers I would expect it will be caught and fixed, but otherwise I wouldn’t expect anything soon.

It’s very rare for a site to need three levels of categories, the answer is nearly always to use tags.

@corinna can you provide reproduction steps for this? I’m assuming this is from the Category settings modal and you try to move it from one parent to another?


Sorry, I mean moving of a thread (I fixed the headline now). When editing a thread, it only offers moving it to categories and sub-categories, not sub-sub-categories.

@Stephen Unfortunately our forum is one of the rare cases, where tags alone do not work. This is because it should actually be four completely different forums. Since there is a big overlap of users and to reduce administrative effort, we decided to combine them.

If you have shell access to the forum, you can also move a topic to a sub-sub-category using these commands (replace <topic_id> and <to_category_id> with the IDs taken from the address bar of the browser):

cd /var/discourse/
./launcher enter app
rails c
Topic.where(id: <topic_id>).update_all(category_id: <to_category_id>)
