Comments Not Showing up!

https://gentlemenslodge.com/fashion/runaway-a-kanye-west-film/comment-page-1/#comment-753

I am having trouble finding the root of why comments are not being displayed, This happened shortly after upgrading to 3.0.1.

This is what shows up on the page or post after a comment is made:

`Warning: call_user_func(eq_comment) [function.call-user-func]: First argument is expected to be a valid callback in /home/content/37/5417637/html/wp-includes/comment-template.php on line 1335

Warning: call_user_func(eq_comment) [function.call-user-func]: First argument is expected to be a valid callback in /home/content/37/5417637/html/wp-includes/comment-template.php on line 1335

Please HELP!!!!
