By default, many wordpress themes are not ready to enable comments and pings (trackbacks) on Wordpess Pages even if you have enabled the comment and pings in Pages setting wordpress admin. Note, it’s in self-hosted WordPress, NOT in WordPress.com.
So, if you want to enable the comments in WordPress Pages, follow this simple steps:
1. Open Appearance -> Editor -> Page.php.
2. Put an additional code and put it after the code
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
and before the code
<?php endwhile; endif; ?>
This is the code you should put somewhere in between above two lines of codes (see the screen shot below):
<?php if (('open' == $post-> comment_status)) { comments_template(); } ?>
3. Remember to Save (click Update File) and you’re done.
Notes:
1. Remember to enable comments and pings in Pages setting (Check ‘Allow Comments’, ‘Allow Pings’)
2. The placement varies from theme to themes. So, try whatever workable for your themes.
3. Refer to wordpress codex on Pages here for more details.
