This Shiv Google CDN Link Not Working. What Should I Do?
<!--[if lt IE 9]>
<script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->
This was happening because the CDN link has been updated for html5shiv.
Try this from CDNJS instead:
<!--[if lt IE 9]>
<script src="https://cdnjs.cloudflare.com/ajax/libs/html5shiv/3.7.3/html5shiv.js"></script>
<![endif]-->
Hoping this will help you :)
