mmilojko on "Theme: Twenty-Thirteen - removing comment box on each page"

Hi, I am new to wordpress.org and am having the exact opposite problem: I am using the twenty-thirteen theme and cannot seem to get the comment box to show up on my posts. Under Setting->Discussion I checked 'Allow people to post comments on new articles" but the comment box still isn't showing up.Do you know how I can do this? Thank you so much!
