drop-down menu not working anymore

Question

The Drop-Down menu on a site I manage has stopped working. The link is here: http://www.lslib.com/ I suspect it might be a jQuery issue but I have installed the jQuery Update module but it still does not seem to work. Any hints on what I may be missing or what needs to be fixed?

Thank you!

I see something like this in my html:

<script type="text/javascript" src="//code.jquery.com/jquery-1.10.2.min.js"></script>
<script type="text/javascript">
<!--//--><![CDATA[//><!--
window.jQuery || document.write("<script src='/sites/all/modules/jquery_update/replace/jquery/1.10/jquery.min.js'>\x3C/script>")
//--><!]]>
</script>
<script type="text/javascript" src="http://www.lslib.com/misc/jquery.once.js?v=1.2"></script>

and I imagine a browser might take jquery 1.2 instead on 1.10. I could npt find which template <script type="text/javascript" src="http://www.lslib.com/misc/jquery.once.js?v=1.2"></script> is coming from. How can I remove this?

Looks like you are getting a javascript error in your superfish.js file.

Uncaught TypeError: Cannot read property 'msie' of undefined

The $.browser method has been removed as of jQuery 1.9.

As stated in the Upgrade Guide you can try using the jQuery Migrate plugin to restore this functionality and let jQuery Tools work or you can use an earlier version of jQuery for your site (1.8 for example)
