Practice section not working?

So, am I the only one for whom the "Practice" tab doesn't work? After I click and the page finishes loading, it gives me a messed-up screen like this. Do I lack some software or something, or is it the site's fault?

  I mentioned this site behavior a post below on this forum. This must be a server side error. You will get these messages until someone won't fix them. Firefox is okay, you do not need a software update. We should be patient, sooner or later everything's gonna work again.
  Personally, I get less of these messages, as I have no new kanji left for my level.
