You need to be using a child theme. If you’re not, let me know and I’ll post some quick instructions on how to get one.
1. Copy this file:
wp-content/themes/hueman/inc/page-title.php
to your child theme:
wp-content/themes/your-child-theme/inc/page-title.php
2. Find this section at the top of the file:
<?php elseif ( is_single() ): ?>
<ul class="meta-single group">
<li class="category"><?php the_category(' <span>/</span> '); ?></li>
<?php if ( comments_open() && ( ot_get_option( 'comment-count' ) != 'off' ) ): ?>
<li class="comments"><a href="<?php comments_link(); ?>"><i class="fa fa-comments-o"></i><?php comments_number( '0', '1', '%' ); ?></a></li>
<?php endif; ?>
</ul>
3. Replace it with this. This changes the page title to use the post title on the single post pages:
<?php elseif ( is_single() ): ?>
<!-- Change post page title to post title
<ul class="meta-single group">
<li class="category"><?php the_category(' <span>/</span> '); ?></li>
<?php if ( comments_open() && ( ot_get_option( 'comment-count' ) != 'off' ) ): ?>
<li class="comments"><a href="<?php comments_link(); ?>"><i class="fa fa-comments-o"></i><?php comments_number( '0', '1', '%' ); ?></a></li>
<?php endif; ?>
</ul>
-->
<h2><?php echo alx_page_title(); ?></h2>
4. Then add this to your custom css:
/* hide default post title on single post pages */
.single .post-title {
display: none;
}
