Can't delete topics - Error 500, rake aborted!

I can’t delete topics and am wondering why that is.

Using the forum software I get a 500 Internal Server Error

Using the console:

$ cd /var/discourse/
$ sudo -s
# ./launcher enter app
# rake destroy:topics["Redaktion"]
Going to delete all topics in the Redaktion category
There are 102 topics to delete in Redaktion category

So, what did I wrong?

rails c
[1] pry(main)> Topic.find(84010).destroy

Killed that topic, but I still can’t delete stuff from the browser.

Its on a desktop pc running on Slack, sitting right next to me, so no provider.

It contains a rather large import from smf. Deleting topics used to work, suddenly stopped. I’m trying to reorganise the import into a structure more suitable to discourse - the old forum had a lot of depth in its structure.

I have now dumped, wiped and reimported the database. That made everything a little bit faster, but the problem remains.

Take a look at this. Are you trying to work with a restricted category which hasn’t got any groups attached to it?

Yes!

I have just tried to delete a topic somewhere else on that forum, and that works. It might indeed be a problem with the import from smf that attached the groups in a weird way.

Thanks for the pointer!

Indeed, adding a group to the category (and all subcategories) did work. Thank you very much.
