Hi guys,

   I'm getting a few lines of whitespace before the xml declaration. If I save the source, remove the whitespace and reload the edited file, it loads perfectly.

There is no whitespace in the masterpages though:

<%@ Master Language="C#" MasterPageFile="~/masterpages/uBlogsyBase.master" AutoEventWireup="true" %>
<%--NOTE: this file must be kept in this format because the xml declaration must be in the first line.--%>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolderDefault" runat="server">
  <script type="text/C#" runat="server">
    protected override void OnPreRender(EventArgs e)
    {
        Response.Clear();
        Response.ContentType = "text/xml";
        Response.ContentEncoding = System.Text.Encoding.UTF8;
    }
</script>
<?xml version="1.0" encoding="UTF-8" ?>
  <umbraco:macro ID="Macro1" runat="server" Alias="uBlogsyRSS" />
</asp:Content>

any thoughts on how to remove the resultant whitespace?

I'm using Umbraco 4.7.1 and uBlogsy 1.3.6.1
