- From the WordPress admin, click on the Posts link (or the link to the post type you want to edit)
- Hover over the post you want to disable comments for and click Quick Edit
- Uncheck Allow Comments on the right side and click Update (for WooCommerce, uncheck Allow Reviews)
To edit multiple posts at a time, check the box to the left of the post title and choose Edit from the Bulk Actions menu at the top of the index, then click Apply.
To disable comments for the whole site going forward, go to> and uncheck Allow people to post comments on new articles . You will still need to Bulk edit all existing posts and pages to disallow comments unless your theme has an option to disable comments site-wide.
