Crayon Syntax Highliter broken

Hi,

I would like to get some help with broken functionality. I have installed few plugins and I wanted to paste some code to my blog. I saw that code button is gone. I disabled all plugins and one by one I found that Page Views Count is messing it up. By messing it up I have in mind broken functionality to add code when writing posts. Code is displayed properly on frontend and issue is with backend.

Would you be so kind and check this issue?

Best Regards
