I have looked through quite a few posts on here dealing with this issue, but none of them seem to solve my problem.

I have imported the jQuery and Bootstrap js files in the right order. Things such as bootstrap panels are working perfectly fine for me.

My script imports are like this:

   <script src=//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js></script>

   <script src=//maxcdn.bootstrapcdn.com/bootstrap/3.3.4/js/bootstrap.min.js></script>

   <link href=//maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css rel=stylesheet>

However, when I try

 $('[data-toggle=popover]').popover();

I get the following message in the Chrome console:

 Uncaught TypeError: $(...).popover is not a function

At first I thought maybe popover was not being included in CDN's copy, so I went ahead and downloaded a local copy with all the plugins included from here:

http://getbootstrap.com/customize/

and got the same error message (re-pointed the script tags towards the local js file).

Doing a search for popover the bootstrap.min.js file:

http://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/js/bootstrap.min.js

Shows that popover is included in the file.
