.NET Publishing - Configuration Error

I recently built a .NET application and am encountering difficult with publishing it. When I try and run it from the server, I get this:

 Configuration Error
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: Unrecognized attribute 'targetFramework'. Note that attribute names are case-sensitive.

Source Error:


Line 16:   <system.web>
Line 17:     <compilation targetFramework="4.5" />
Line 18:     <httpRuntime targetFramework="4.5" />
Line 19:     <pages>
Line 20:       <namespaces>


Source File: D:\Webroot\fleet\web.config    Line: 18 

I did some research and it indicated that I needed to ensure the server Application Pool was set at 4.0. I changed that. Same issue. So I tried changing the framework version to 4.0 in the Web.config. Still no success (the server does not meet the requirements for 4.5). So I decided I would remove the httpRunTime tag and republish. After that, I get a Parser error:

Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

Parser Error Message: The file '/Site.Master' does not exist.

Source Error:


Line 1:  <%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Fleet_Maintenance._Default" %>
Line 2:  
Line 3:  <asp:Content ID="BodyContent" ContentPlaceHolderID="MainContent" runat="server">


Source File: /fleet/default.aspx    Line: 1 

I am a bit at a loss and would really appreciate any help. Here is a portion of my Web.config.
