After building and uploading my project to my host I get a blank page. No errors just a blank page. I have done the following:

- Ensured all read/write permissions ont he root and child objects

-Uploaded all additional files/ Local .sdf database and such

-Dedicated application pool

-Windows integrated authentication

My host seems to think its an issue with the content of my default.aspx file which i havent changed since i insatlled umbraco or modified it:

<%@ Page language="c#" Codebehind="default.aspx.cs" AutoEventWireup="True" Inherits="umbraco.UmbracoDefault" trace="true" validateRequest="false" %>

Its looking for default.aspx.cs which none of my projects have and i cant do a /find for them.

Any ideas? Kind regards.
