This KB article details why certain users are not able to view/edit digital signage locations and/or players in Four Winds Interactive versions 5.3 and later as implemented by the Illinois Digital Signage Service and what to do if such abilities are required.
When trying to access the properties of a Location in the Content Manager tree or the properties of a Content Player, a message for insufficient permissions appears.
Before the implementation of Four Winds Interactive (FWi)
Content Manager shared database model, many users were accustomed to having
full access to view and edit all properties within the system. With the
implementation of the shared database model, this access more restricted to
prevent accidental changes/deletions to important settings.
Users who receive a message such as, You don’t have sufficient permissions to edit the properties for… but have the need to do so should contact us at firstname.lastname@example.org and we'll be glad to investigate the issue for you.
