Dropdown menus not working

[Felix]

Hi,

You have the jquery library called 2 times:
1) first time in the header

Code:

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js?v=1.7.1"></script>

2) second time in the footer

Code:

<script src="http://earthscienceiscool.net/theme/Bootstrap3/js/jquery-1.10.2.min.js"></script>
