Interesting. How did you manage to delete those topics? You shouldn’t be allowed to delete them in the UI.
First, let’s see if the topics are really gone.
./launcher enter app
rails c
Topic.with_deleted.exists?(SiteSetting.guidelines_topic_id)
Topic.with_deleted.exists?(SiteSetting.tos_topic_id)
If the topics are really gone, create two new topics in the Staff category and assign the topic ids in the rails console to the site settings.
SiteSetting.guidelines_topic_id = 4711 # replace with topic id
SiteSetting.tos_topic_id = 4712 # replace with topic id
SiteSetting.default_locale
And then replace the content of those topics by using the “Manual Update” described in Update seeded categories and topics
