One common problem facing WordPress users is the amount of spam comments.
There are some spam-fighting tools such as Akismet and Mollom, but some of users prefer to turn off comments entirely.
One of our students wanted to disable WordPress comments, so we created this step-by-step tutorial for him.
- Go to Settings > Discussion.
Uncheck the "Allow people to post comments on new articles" and the "Allow link notifications from other blogs (pingbacks and trackbacks) " settings.
The pingbacks feature of WordPress is like commenting for computers. It allows other blogs to leave a comment/link on your blog to their blog if they mention you. Unfortunately, in many cases it's not useful and is a bit like link-spam.
Finally, at the bottom, save your changes and you're done. If for some reason you still get commenting at the bottom of some posts, you'll need to go to those individual posts and uncheck the settings for commenting.
