By default, WordPress has comments enabled on new posts and pages, but you can check to make sure that comments are enabled in your WordPress site by following these steps:

1. Log in to your WordPress dashboard.
2. Click on “Settings” in the left-hand menu and then click on “Discussion”.
3. Under “Default article settings”, make sure the “Allow people to post comments on new articles” box is checked.
4. Under “Other comment settings”, you can choose to manually approve comments, require users to be registered and logged in to comment, and other options.
5. Click “Save Changes” at the bottom of the page.

Now, when you create a new post or page, comments should be enabled by default. If you want to disable comments on a specific post or page, you can do so by editing the post or page and unchecking the “Allow Comments” option in the Discussion settings.
