Comment section for posts not showing up

Hello,

I am having problems with the comment section not showing up for posts on my website.

I have tried every solution so far:

+ Enabling comments from Settings > Discussion.
+ “Allow people to post comments on new articles” is checked
+ Comment must be manually approved is UNchecked
+ Automatically close comments on articles older than X days is UNchecked
+ Making sure the “Allow Comments” in the meta box for every post is checked.
+ Temporarily disabling all plug-ins to check if there’s conflict with the comments sections
+ Tried using another theme.

But all those were unsuccessful.

The comment box appears on the pages though, but not on posts. When I try to create a new post and when I check the preview, the comment section is also not showing up.But when I try to create a new page, the comment section is present.

I am at a total lost as to why this is happening since the comment section seem to work on pages but not on posts.

Any kind of help on this problem would be GREATLY appreciated.

THANK YOU in advance.
