A few months ago I installed Discourse, added some topics as Index Topic in the Documentation Mode section. Everything worked as expected. backed up everything, deleted the Digital Ocean account, etc. A few days ago I installed Discourse again and restored everything from the backup file I created…

Just checking - have you seen this? [圖片] Discourse Doc Categories 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: bundle exec rake doc_categories:build_sidebar # if runni…

Thank you for the link. Since I’m still building the whole structure, I ended up just creating a new topic, copying and pasting the content from the old one, and delete the old topic. I only had 2 of those anyway. So, my question is: is that rake task something I need to do every time I update Dis…

Awesome! Thank you for clarifying! :raising_hands:

Hey fellow Nat, I’m acknowledging this issue here. I think there is a real problem but will need to reliably repro this. Will get back here sometime next week with good news hopefully.

@nathank quick question, do you have discourse-calendar enabled?
