Doesn't collapse anymore

Hi everybody,
The comment isn’t being collapsed anymore. I am not sure when this happened.
I uploaded the newest collapse o’matic plugin, but still nothing.
What can be the problem?
Here is the comment that should be collapsed: http://www.tina-turner.nl/blog/flagg-grove-school/
