Fatal error

Certain pages, such as editing posts, come up as so –

Fatal error: Call to undefined function enqueue_comment_hotkeys_js() in /home2/crazyrey/public_html/wordpress/wp-admin/post.php on line 148

I’ve tried adding in the 2.7 files a few times but it still comes up. Additionally, the image upload page (on the page edit) is a little messed up, housing a text box with the following –

EXCEPTION: message: init_settings is undefined

Any help?
