If you have recently upgraded your version of Bootstrap from 2 to 3 then you might be wondering why some of your popovers are not working as you might expect.

One potential reason is that there used to be a class called .popover-inner, this now seems to be directly replaced with .popover-content.

I had some styled nested inside of .popover-inner which magically stopped applying after the update.
