problem

i want to make a move but no chess diagram is showing up.i have tried several times but still not getting the game to show up.want is the problem.

One common suggestion is to clear your cache and perhaps reboot.

The other common suggestions are:
change the size of your board
change the piece set
If either of those works, try changing back again (it's like rebooting your chess page, it reloads the file copies).
