Sharepoint server publishing feature was activated on one of my SharePoint sites, but it's not showing hide ribbon in Site Actions.
Also when we edit the page, it's appending the parameters “?PageView=Shared&InitialTabId=Ribbon.WebPartPage&VisibilityContext=WSSWebPartPage” to the address bar insted of "?ControlMode=Edit&DisplayMode=Design".
NB : In the navigation setting the "Ribbon" and "Hide Ribbon" commands are already set as "true"
