Lightbox 2.8.1 issue

I am trying to get lightbox to work on a local test server install of Omeka with the default theme (Thanks Roy). I have followed the instructions here: https://omeka.org/codex/Adding_LightBox_to_Omeka but I am getting the following error in Firefox Debug window:

<script type="text/javascript">
//<!--
window.jQuery || document.write("<script type=\"text\/javascript\" src=\"http:\/\/10.11.37.53\/omeka\/application\/views\/scripts\/javascripts\/vendor\/jquery.js\" charset=\"utf-8\"><\/script>") //-->
</script>

looks like the jquery.js is being commented out and I'm not sure why or how to fix this. Any help appreciated!

Those comments aren't an error, they're just what our framework outputs when it directly generates JavaScript. Is that actually the error you got in the console? It doesn't really look like an error, rather just a part of the page markup.
