Graphics | After Pressing a Button, the Board Won't Show Up

[iceswordmaster]

Earlier today, I was doing problems and then the web page started lagging and showing the solution and making moves on its own. Hoping to solve this, I hit a button that read something like 'Go to Java Version'. When I reloaded the page, everything was there but the board that was supposed to represent the problem. Below is a basic representation of what happened.
