Hello,

I'm using a Masterpage with .NET 4.0 and a RadSkinManager. Without obviously changing anything in the masterpage, I'm getting a NRE in one of my 3 content pages. The question is why is this only happening in one page and how to get RadSkinManager applied continously to all content pages?
My masterpage head is the following:

<head id="Head1" runat="server">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<title></title>

<telerik:RadSkinManager ID="rsm" runat="server" Skin="WebBlue"></telerik:RadSkinManager>

<link href="~/Styles/Site.css" rel="stylesheet" type="text/css" />

<asp:ContentPlaceHolder ID="HeadContent" runat="server"></asp:ContentPlaceHolder>

</head>

The error:

[NullReferenceException: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.]

Telerik.Web.UI.RadSkinManager.Page_PreRender(Object sender, EventArgs e) +67

System.EventHandler.Invoke(Object sender, EventArgs e) +0

System.Web.UI.Control.OnPreRender(EventArgs e) +92

System.Web.UI.Control.PreRenderRecursiveInternal() +83

System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +974
