Popup with error (/[object Object])

Hi.

I’m using Crayon Syntax Highlighter 2.3.0, but, when I activate it, whenever I open a blog entry with code, it opens a popup:
———–
Not Found

The requested URL /[object Object] was not found on this server.
————
I used this plugin in the past with no problem, but I don’t know from wchich version it started to act like that and don’t know what to do (i.e.: downgrade, touch the code, disable it…).

Any help?
