Cannot see board

I've been playing chess on my Kindle without any problem, until yesterday. Now, when I select one of my games in progress the board doesn't display.
Any ideas?

It's possible that you have something in your cache that's causing the problem. Try logging into one of the variant sites such as chessatwork.com or timeforchess.com. If the problem disappears then clearing your cache will fix it for your regular site.
