I am trying to create a scenario where users can create child documents but NOT edit the parent (ie news articles - some are from a node they can't edit, but they can add comments underneath).

My idea was to hide the 'Save', 'Save and publish', 'Unpublish' buttons for the parent nodes : I have tried putting Save Save and publish Unpublish

in the Names field and selecting 'Hide Buttons' but they still see the buttons.

I know the package is working as I can hide panels.

Can you help?

Thanks
