I read most of issues topic about comment, but my comment still doesn't work

Now my comment in production only show a title “Leave a comment”, there is an empty area under “Leave a comment” can not input comments. Could you please help me to fix? Thank you

I put below code to _layouts\single.html already:
{% if jekyll.environment == ‘production’ and site.comments.provider and page.comments %}
{% include comments.html %}
{% endif %}

comment: true
and set a value to provider

You need to register for a Disqus account and add your shortname to the config. You currently have it set to blank.

Thank you so much, let me try
