[Plugin: WP-Markdown] WP Markdown Javascript error?

Hi,

I’m trying to use WP Markdown on my bbpress forum. I have installed it and ticked all the boxes in the Writing menu.

It doesn’t quite display correctly on the bbpress pages – the WordPress WYSIWYG is still present. Here is a screenshot:

I don’t really have a clue about JavaScript but this error is coming up in the console when you try to click on the Markdown toolbar (like bold, italic, etc).
