Hi Freddy Buskens, I downloaded and uploaded the _starter_publishing.master in SharePoint Designer, and added a new page pointing to the new master page. The page only contains the following, but when I try it in any browser, I got an error below. Any clue? Please help!
<%@ page language="C#" masterpagefile="../_starter_publishing.master" %>
<asp:content xmlns:asp="asp" id="content1" runat="server" contentplaceholderid="IWS_WH_CPH_Content">
</asp:content>
