More tag is not working

Yup, same problem More tag doesn’t work no matter what I do. Using theme Vita 1.6. Posts to author unanswered. Any help? Below is the code to my index page. Similar code is on the page.php. Thanks in advance.

<?php get_header(); ?>

<div id="content-wrap">
  <div id="content">
    <div class="gap">
      <?php if (have_posts()) : ?>
      <?php while (have_posts()) : the_post(); ?>
      <div class="post" id="post-<?php the_ID(); ?>">
        <h2 class="post-title"><a class="intitle" href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>">
          <?php the_title(); ?>
          </a> <span class="commr">
          <?php comments_popup_link('0', '1', '%'); ?>
          </span></h2>
        <div class="timr"> Posted on
          <?php the_time('F d, Y') ?>
          by
          <?php the_author() ?>
          <?php edit_post_link('e', '<span class="editr">[', '] </span>'); ?>
        </div>
        <div class="entry">
          <?php the_content('Read the rest of this entry &rarr;'); ?>
        </div>
        <p class="postmetadata">
          <?php the_tags('Tags: ',', ','<br />');?>
          <span class="catr">Category
          <?php the_category(', ') ?>
          </span> </p>
      </div>
      <?php endwhile; ?>

      <?php if(function_exists('wp_pagenavi')) { wp_pagenavi(); } else { ?>
      <div class="navigation">
        <div class="alignleft">
          <?php next_posts_link('&larr; Previous Entries') ?>
        </div>
        <div class="alignright">
          <?php previous_posts_link('Next Entries &rarr;') ?>
        </div>
      </div>
    <?php } ?>

      <?php else : ?>
      <h2 class="center">Not Found</h2>
      <p class="center">Sorry, but you are looking for something that isn't here.</p>
      <?php include (TEMPLATEPATH . "/searchform.php"); ?>
      <?php endif; ?>
</div> <!-- /gap -->
</div> <!-- /content -->
</div> <!-- /content-wrap -->
<?php get_sidebar(); ?>
<?php get_footer(); ?>

Absolutely. Clicking the button in the post text menu bar (under HTML). There’s code similar to my index page on my page.php as well if that matters. When I publish or preview the page, all the text shows up in a single frame with no “more” in site. I’ve been working around with a hyperlink to a child page but it’s a funky way to do it since I have to redirect comments back to get the comment counter to register on the original post page. A lot of people seem to be having a similar problem…
Thanks.

I have managed to resolve this for myself.

I was tooling around, and fooled around with a few settings. Seems that when the newest WP version needs to be set to full text render to recognize the more tags as we are used to.

WP Dashboard > settings > reading > For each article in feed show > and switch the radio button to “full text”.

That fixed it for me.

Hope that helps someone else!
Cheers!
