When I look at the "active questions" page, I get an empty list of questions (the "number of question" on the side also displays $0$). That's true for both the main site and the meta. Is this happening only to me or to other people too? And why is this happening?
Edit $1$: This happens not only for the "active questions" page, but also for "newest", "unanswered", etc.
Edit $2$: Now everything is back to normal. I'd like to know what happened, though.
