I have a promoted links Webpart on a page and I've configured permissions so that only certain groups can view it. However, users who are not granted access to the webpart can see a message from the webpart that reads "The list is empty. Add tiles from the All Promoted Links view". I'd like to remove this because it's misleading to the user who doesn't need to see the webpart at all.
I'm using Foundation 2013 so I can't use audience targeting to control the content.
How else can I remove this message? CSS?
Thanks in advance.
