It looks like you need to go into your Comments settings to allow people who aren’t logged in to comment as well.
On your dashboard go to Settings>Discussion
Make sure that
‘Allow people to post comments on new articles’
‘Anyone posts a comment’
are checked –
Make sure that
‘Users must be registered and logged in to comment’
‘A comment is held for moderation’
‘Comment author must have a previously approved comment’
are un checked until you see that comments start to populate.
I would make sure your email is correct in your site because I like to make sure that I am in control of what is being posted on my site by checking ‘A comment is held for moderation’. It will email you when someone comments so that you can moderate it – if not you can check the Comments tab in your WordPress dashboard.
Here’s a great overview of comment settings in the WordPress codex…
