When using WordPress as a CMS, you’ll undoubtedly want to disable comments for some Page or even Posts. This is a popular question (especially among new WordPress users). First – navigate to your page or post (edit more). Then go to the top of the page and find Screen option . Make sure you have the Discussion activated. Then, on your page find the box and uncheck the “Allow comments” and “Allow trackbacks and pingbacks on this page”. That should hide the comment box. You can check the screenshots below.
If you want to disable all WordPress comments on all future articles by default, you can go to Settings → Discussion and deselect “Allow people to post comments on new articles”. You can enable comments on future articles. This just disables them by default so you don’t have to always perform that extra step.
