Lots of discussions are suggesting uncheck the comment in Admin, where it might work for someone, at least not me;
Also someone suggest go into the database to forcely change the comment status to "Closed", it does seem to almost remove the "Leave a Reply" section, unfortunately still has a "Comment Closed" section on the page.
While understanding this has nothing to do with specific theme, I wonder how a post/page is generated? using which php file? maybe the section can be removed by deleting some php code from there?
Thank you very much.
