The blog page you linked to is the archive (post listing) page, not a single post page where comment thingy is usually going on.
Right now you got only 1 blog post, so it might be hard to tell which page is an archive or single, try making a few more posts.
There is something else too. On your blog’s archive (post listing) page, there is a CSS code in your child theme that display:none the post title, so what you see as the post title is not the real one but a line of text wrapped in H2 in the content area.
Since the real post title is display:none, there is no clickable link that leads to the single post page. So we must remove the display:none from your child theme style. And when we did that the real title will lead to this page https://radicalurge.com/hello-world which is the single post page and there is commenting system going on there.
I suppose you forgot or simply not aware that you need to change the permalink from hello-world to everything-is-connected as your real post title.
Thank you for your concise explanation – very helpful.
I had removed the blog title as the client wants the title below the feature photo, but I forgot about the linking part. Good to have a friendly reminder.
@janburg No problems, I’m happy to help out the community when I can.
In regard to your client wanting the title beneath the featured image, I believe the theme you are using (Genesis Frameworks) has ability to do that, but this forum is for themes hosted over here (wordpress.org) and WP related topic only, so what I can do is to encourage you to make use of your theme’s support channel on this matter. Just ask them how to switch post title and post image.
On a separate note, please make sure the logo (site header image) looks okay both in desktop and mobile device. Using Chrome’s web dev tool here, I could see the site header image gets cut off in mobile version.
