Right now it seems that a bug is affecting MO: reputation and badges are no longer displayed next to the users' names.
This happens both on the front page:
as well as on pages of individual questions:
Furthermore, the reputation pop-up is also not displayed when I hover the mouse cursor above a user's name.
This seems to be a MO-only bug, since it doesn't manifest itself on the other SE sites of which I am a user. This also doesn't manifest itself on Meta.
