Can't get MVC MiniProfiler to show on ASP.net website

My web.config file:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <configSections>
    <section name="rewriter" requirePermission="false" type="Intelligencia.UrlRewriter.Configuration.RewriterConfigurationSectionHandler, Intelligencia.UrlRewriter" />

          <remove name="UrlRewriter" />
          <add name="UrlRewriter" type="Intelligencia.UrlRewriter.RewriterHttpModule,Intelligencia.UrlRewriter" preCondition="managedHandler" />
        </modules>
      <handlers>
        <add name="MiniProfiler" path="mini-profiler-resources/*" verb="*" type="System.Web.Routing.UrlRoutingModule" resourceType="Unspecified" preCondition="integratedMode" />
      </handlers>
    </system.webServer>    
</configuration>

My global.asax:

using System;
using System.Web;
using StackExchange.Profiling;

namespace C3
{
    public class Global : HttpApplication
    {
        protected void Application_BeginRequest(object sender, EventArgs e)
        {
            // Force to HTTPS
            if (!HttpContext.Current.Request.IsSecureConnection)
            {
                Response.Redirect(Settings.SecureRootDomain + HttpContext.Current.Request.RawUrl);
            }

            if (Request.IsLocal)
            {
                MiniProfiler.Start();
            } 
        }

        protected void Application_EndRequest()
        {
            MiniProfiler.Stop();
        }
    }
}

Content page:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="C3.Default"%>
<%@ Import Namespace="C3.Code" %>
<%@ Import Namespace="StackExchange.Profiling" %>
<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <%
        SEO.CheckURL("/");
    %>
    <title></title>
    <%=MiniProfiler.RenderIncludes() %>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        dum de dum
    </div>
    </form>

</body>
</html>

And code behind:

protected void Page_Load(object sender, EventArgs e)
{
    var profiler = MiniProfiler.Current; // it's ok if this is null
    using (profiler.Step("Set page title"))
    {
        Page.Title = "Home Page";
    }
    using (profiler.Step("Doing complex stuff"))
    {
        using (profiler.Step("Step A"))
        { // something more interesting here
            Thread.Sleep(100);
        }
        using (profiler.Step("Step B"))
        { // and here
            Thread.Sleep(250);
        }
    }
}

Any ideas why the MiniProfiler isn't showing anything?

Update

If I visit https://127.0.0.1:3333/mini-profiler-resources/includes.js in my browser, it's returning the JS file! It's just not rendering the includes on the page itself.

If I visit /mini-profiler-resources/results it throws the error:

Ensure pages showing the MiniProfiler don't contain an ignored path in the URL specified by MiniProfiler.Settings.IgnoredPaths, which by default has /content/, /scripts/ and /favicon.ico. A page with the URL /content/Default.aspx won't show the MiniProfiler, whereas /Pages/Default.aspx will show it.

Alternatively, remove /content/ from MiniProfiler.Settings.IgnoredPaths.
