Posts empty when upgrade Crayon syntax highlighter 2.4.1

I have problem when upgrade Crayon 2.4.1,
Currently on my site using the crayon Version 1.17, it works fine.
But there is a strange, if i have more than 12 [CODE] in the post, this page will be empty.

It’s be the same problem when i upgrade the Crayon 2.4.1
– I create a post using Crayon, this page is empty.
– And when i view the other posts(without use Crayon), i see the comments in the bottom switch to tinymce not a textarea.
Is there any settings to fix this?

Thanks,
Lam
