How to enable comments options?

1. On page –> Screen Options –> check Discussion –> Discussion –> Allow commets –> I have checked on discussion options.

2. Settings –> Discussion –> I have checked on Allow people to post comments on new articles.

3. I also have this code in my theme: <?php comments_template(); ?>

But the comment form is still not visible. What else do I have to do?

Go to the page.php template of your theme and check if <?php comments_template(); ?> is added there. If it isn’t, then you need to add this line below your page content rendering section.
