Hi Corina, 

Here's how you can do it:

1. Bulk Edit Posts:
   • Go to your WordPress dashboard and navigate to "Posts" > "All Posts".
   • Check the box next to the posts for which you want to deactivate comments. You can select multiple posts by checking the boxes next to them.
   • Once you've selected the posts, click on the "Bulk Actions" dropdown menu above the posts list.
   • Choose "Edit" from the dropdown menu and then click the "Apply" button.
2. Disable Comments:
   • After clicking "Apply," you'll see options appear below the posts list.
   • Look for the "Comments" option and change it to "Do not allow" or "Do not allow, hide existing" (depending on whether you want to disable comments completely or hide existing comments).
   • Finally, click the "Update" button to apply the changes to the selected posts.
3. Verify Changes:
   • After updating the posts, verify that comments have been disabled by visiting the individual posts in your WordPress dashboard and ensuring that the comment section is no longer visible.
