I made my comments disappear?

Hi all!

Let me start out by saying I am not very tech savvy, so I probably did something silly. And it would have been a year ago when I created my page.

Here’s my question. I have comments that I would like to appear on my blog. People have commented. I have approved the comments. They are not visible anywhere. I have a vague memory of doing… something to the comments section when I first made my blog so that it would have a “cleaner look”. ?? When I run the firebug over my page, though, I can’t find anything that will help me locate my problem.

Here’s my page: https://www.blog.megwilsonphotography.com

Can anyone help?
Either fix whatever I did, or is there a plugin for comments?
Thanks!
