Just faced with the problem that working functionality stop working as soon as add VM component/module on the page. After investigation, I reilize that VM loads jQuery from googleapis.com but it appears in the page as follows: <script src="//ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js" type="text/javascript"></script> As you can see, there is no http prefix for the url, so I assumed that because of that it doesn't work aтв I fixed the bug in the files as it mentioned in the subject, lines 469, 470. Hope it can help somebody too.
