Depending on your blog or site’s purpose, you may not want to allow readers to comment, or to show commenting aspects on your posts and pages–such as when your are using WordPress to build a website. This is the case for a real estate agent/client of mine, who had me set up several individual WordPress-hosted sites for her listings:
- www.LuxuryCdMhome.com (Theme: Twenty Eleven – the default theme for last year)
- www.1704WOceanfront.com (Theme: ColorWay)
- www.3336ViaLido.com (Theme: Minimatica)
1) To remove your commenting functions from your site, I would start with first and foremost doing a search on how to do so with your particular installed theme, and by going with the instructions given by the theme’s developer.
2) If that doesn’t work, then edit your discussion settings as shown above (click for a bigger view): Dashboard–>Settings–>Discussion. Uncheck the box that says “allow people to post comments on new articles”, so that future posts will not have commenting enabled. Also change “Automatically close comments on articles older than  days” to one day. I would also check the box for “An administrator must always approve the comment”.
Editing your discussion settings will disable commenting, but the front side of your blog posts will have the words “comments are closed” or “comments off”. If you do not want these words to be visible, read the following steps.
3) To remove all of the commenting information, you will have to edit the actual theme files. It’s super important to always make a copy of the file you will be editing, just in case you ever want to allow comments at a later time.
You can also edit your single.php and/or page.php files in your theme (make a copy of both the original and the edited version, too–just in case you want to have the comments at a later time, or when you update your theme and it goes back to the default single.php file). Just find this verbiage: <?php comments_template(); ?> and delete it. (Tip from wprecipes)
You may also need to delete all of the coding within the comments.php file. (Once again, make a copy–just in case!)
