By default, Headway does not enable comments for WordPress pages. However, enabling comments for WordPress pages is pretty easy. Depending on your setup, the options are different. You first need to understand how Headway’s inheritance works.
If you want comments enabled for posts and pages and you want them to have the same layout, you just need to customize the Single layout in the Headway Visual Editor. You will edit the options for the content block on the Single layout to always show comments.
Click on the content block options for the Single Layout, then click on Display. Where it says “Comments Visibility” you will change that to show “Always Show Comments”. See the screenshot below.
If instead you only wanted comments enabled on pages or if you want the single page layouts and single post layouts to be different, then you would need to customize the Single > Page layout in the Visual Editor using the steps I described above.
