Check Settings->Discussion.

Go to dashboard > posts > posts > mouse over post and click on edit. Scroll down and check comments on.

If you do not see comments, click on screen options in upper right corner and turn discussion on.

as i said i already checked discussion then also i m mentioning checked one option below :
Attempt to notify any blogs linked to from the article.
Allow link notifications from other blogs (pingbacks and trackbacks.)
Allow people to post comments on new articles
Comment author must fill out name and e-mail
Enable threaded (nested) comments levels deep
Anyone posts a comment
A comment is held for moderation
