Comments are turned on by default for your posts and pages. You can change the default comment setting or disable individual post/page comments by following the steps in this article.
Navigate to the post or page and click on the edit button. Once you’re in the edit view, click on the screen options menu. It’s located in your admin bar and is usually positioned at the top right of your screen.
Find the “Discussion” option and click on it.
Uncheck the “Allow comments” and/or “Allow trackbacks and pingbacks on this page” to disable comments for the page.
Go to the dashboard view and then click on the posts or pages tab. Select multiple articles by click on the check box next to their name. You can select everything by clicking the check box next to the title column heading. Once you have the articles selected, click on the bulk actions drop down and select “Edit” and then click apply.
Look for the comments option and select “Do not allow” and then click the update button to save the changes.
As I’ve said earlier in the article, WordPress has comments enabled by default. This option will disable comments on all future articles. If you have comments on an existing article, you will need to either delete them or disable comments for the individual page.
Go to the dashboard view and look for the discussion option.
Find the default articles setting section and uncheck the “Allow people to post comments on new articles” option.
New posts and pages will now have their comments disabled.
This option will disable comments for an article after a set amount of days from the time it was published. Go to your dashboard view and click on the discussion link.
Look for the setting shown below. Make sure fill in the amount of days and then enable it.
