i have set the externaldialogpath for my editor but it seems that it is still taking the old dialog code.
i have confirm the path to the dialog is correct
the code is a custom web part for sharepoint 2013
<telerik:RadEditor ID="RadEditor1" runat="server" ExternalDialogsPath="/inetpub/wwwroot/wss/VirtualDirectories/siteproject/externalFiles/TelerikEditorDialogs/" DialogHandlerUrl="~/Telerik.Web.UI.DialogHandler.axd" OnClientLoad="OnClientLoad"></telerik:RadEditor>
