Disqus not showing up - Getting default comment form

Question

I installed disqus on my wordpress site.
Bt it is not showing up. It says it will replace default comment form.

I'm showing it like this:

<?php comment_form(); ?>

But, default comment form is getting loaded.

Am I missing something?

Note: I am using custom theme. Do I need to do something in it?

This question seems to be the same as yours and answer says to use this instead.

<?php comments_template(); ?>

Not sure if it works on localhost by the way.
