In the last 24 hours on the Chessbase website when trying to play through games a message appears alongside the board (where the moves normally appear) 'You must have JavaScript enabled to replay this game'
I have checked to make sure that I hadn't inadvertently changed any of my settings in Java but they all appear normal.
I've even downloaded the latest version from Java website just in case.
Have also switched the machine off and switched it back on again!!

I normally use Chrome but the same message appears in Internet Explorer, I haven't checked any other web browsers.
I've tried accessing with a different lap top with the same results.
So have come to the conclusion it is a Chessbase problem.
Anyone got any bright ideas?
