Telerik ReportViewer Cors Error
<p>I'm trying to use Telerik Reporting MVC but when i run this code </p>

<p>$(window).load(function () {</p>

<pre><code>    $("#reportViewer1")
        .telerik_ReportViewer({
            serviceUrl: "http://127.0.0.1:80/api/reports/",
            templateUrl: '/ReportViewer/templates/telerikReportViewerTemplate.html',
            reportSource: {
                report: "Vehicles.trdx",
                //parameters: {
                //    ReportYear: "2003"
                //}
            },
            viewMode: "ViewModes.INTERACTIVE",
            scaleMode: "ScaleModes.SPECIFIC",
            scale: "1.0"
        });
});
</code></pre>

<p>I always get a message saying:</p>

<blockquote>
  <p>No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin '<a href="http://localhost:63600" rel="nofollow">http://localhost:63600</a>' is therefore not allowed access. The response had HTTP status code 500.</p>

<p>Can someone help?</p>
