@ld57 Your readonly rest access control is a document in an index .readonlyrest
If you do: GET .readonlyrest/_search
You’ll see one result, probably with _id: 1
I had the same issue as you, followed by the issue you linked to about not being able to delete indices. To fix it, I (in Kibana):
Copied the _source document from the ROR index
Pasted into the dev console
Added kibana_access: admin to my kibana ACL rule
POST .readonlyrest/_doc/1 the document you have just edited to update the access control rules.
I can’t remember, but you may need to logout/login again to see the change but the ROR settings are now under the logout button. If you set it to admin you’ll get an “a” in the red box, the “u” means unrestricted.
Obviously make sure you have a copy before you POST in case you made a mistake and need to change it. It will save you downgrading and upgrading, but that might be safer.
I have made a PR for the docs to add information about the unrestricted flag.
unfortunately I tested both entries (admin or unregistered) , but no way, with 1.20 on 7.4.2 , give no result ,
i mean no interface for RoR, no button…
