You need to change this:
<!--[if lt IE 9]>
<script src="https://oss.maxcdn.com/libs/html5shiv/3.7.0/html5shiv.js"></script>
<script src="https://oss.maxcdn.com/libs/respond.js/1.3.0/respond.min.js"></script>
<![endif]-->
To something like this (using whatever is the relative path for your site):
<!--[if lt IE 9]>
<script src="/path/to/your/libs/html5shiv/3.7.0/html5shiv.js"></script>
<script src="/path/to/your/libs/respond.js/1.3.0/respond.min.js"></script>
<![endif]-->
