Editing blogengine site - errors

Mar 3, 2015 at 9:56 AM

I am new to blogengine. I have it installed. I opened visual studio 2013 and opened the web site. went to edit default.aspx and i get an error from VS that the page references a masterpage but none is specified.

2 warnings:
Warning 1 File 'default.aspx.cs' was not found. W:\Work\Web Sites\BlogEngine31\default.aspx 1 79 BlogEngine31
Warning 2 Unrecognized tag prefix or device filter 'asp'. W:\Work\Web Sites\BlogEngine31\default.aspx 3 2 BlogEngine31

top line of code is:
<%@ Page Language="C#" AutoEventWireup="true" Inherits="_default" Codebehind="default.aspx.cs" %>

There seems to be no master page mentioned in that line

I havent changed any files since upzipping. I have set permissions to app_data as per instructions

Can anyone help please?
