Solo-chess bug

Hi, I'm having a technical issue with solo-chess. For the last week or so when I try to play the solo-chess puzzles (which I love), I get what you can see in the screenshot below. There's no board, the top headers are covered by red squares, and nothing is clickable. I would have filed a bug but the help section doesn't expand when I hover over it. This happens with both firefox and chrome. I've also tried clearing my cache but it didn't help. Is this a known issue, and is there anything I can do to resolve it? I know how to inspect the page and edit attributes which can occasionally get around bugs like this. Thanks.

I'm sorry for the trouble here; we are working on it. 

Thanks, good to hear.

I'm having the same issues trying to load Solo Chess. Is there anything that can be done from a users perspective to allow Solo play?  Really miss this practicing on this game.
