Ah, thanks !! I was in the "All unique tag objects" page which doesn't allow me to edit but I can do so in the "List by field value pair" page.
This is probably not related to this topic but is it possible to change the default permission when a user creates a new tag? At the moment, it is set to Private, I would like to change it to App.
Can you provide more details for your question please? What were you doing when you got this message? What kind of Splunk deployment? Include as much information as possible for people to help you here.
