    The answer entry applet isn’t showing up correctly for me on this post or the previous one. It was working fine on the ones before, though.

      I recently had the answer-entry stop appearing for me as well. Here’s how I fixed it:

      First, a while back, when it first disappeared (because had switched to https, but was still on http:), I was able to bring it back by enabling “mixed content” within my browser (allowing both http and https on the same page).

      Now, with also using https I had to enable thid-party cookies for, (so that a cookie from could be saved). After I did that, the answer-entry applet appeared again.

      [Within chrome, at least, the controls for this are behind an icon at the right of the URL bar (just to the left of the star) which is apparently intended to look like a cookie, with a little white X in a red square in front of it.]

        Nope, that hasn’t worked at all. Only this one, the previous one, and the next one aren’t showing up correctly for me; all other answer input widgets seem to work fine.
