javascript is not working after upgrade wordpress current version

Hi,

After upgrade current latest version of wordpress 4.0 , javascript is not working.

I was wrote following simple code in text mode of page:

<h1>Free Sample Templates:</h1>
<!-- MyTemplateStorage.com Affiliate Interface. -->
<script src="http://www.templatehelp.com/codes/pr_interface_samples.php?bgcolor=%23FFFFFF&iw=730&ih=550&pr_code=2BF5BTJ98pT3v1AsO6J91Os0uHDb70&" type="text/javascript"></script>
<!-- End Of MyTemplateStorage.com Affiliate Interface. -->

That is available in page. You can see via view page source also.

Please look page # https://www.webhostingpeople.net/free-sample-templates.html

In my local computer with old wordpress version it is still working fine.

Please guide me how can We fix it ?
