No Comment ‘Submit’ Button

I’m having trouble with the ‘submit’ button for comments on my blog. I’ve had about 10 comments left on the post today, so I know it works for some people, however I just got three emails from people saying there isn’t a submit button for them to add their comment. I tested it myself by logging out and trying to leave a comment and sure enough- there isn’t any way to submit the comment.

I don’t know why it would work for some people and not others. Has anyone else had this problem and been able to fix it?

Here is a link to the blog post.
