  Page Editor conflict with master pages

Page Editor conflicts with master pages.

Workaround.

Include the placeholder with key=”webedit” to host the Page Editor buttons. This placeholder can be inserted either on the master page or inside of <asp:content /> on the content pages (layouts).

<sc:placeholder key="webedit" runat="server" />
