I am not pretty sure where's the problem, make sure that:
(1) You have included the bootstrap css
(2) Try insert the data-container attr. and and "id" as such:
<li>Commercial Use <a href="#" id="myPopovers" data-toggle="popover" title="" data-content="And here's some amazing content. It's very engaging. right?" role="button" data-original-title="A Title" data-container="body"><i class="fa fa-question-circle"></i></a></li>
(3) From bootstrap, it says that:
**Opt-in functionality**
For performance reasons, the Tooltip and Popover data-apis are opt-in, meaning you must initialize them yourself.
This means you should initialise it via JavaScript as such:
$(document).ready(function(){
$("#myPopovers").popover(); // or $("#myPopovers").popover('show');
});
