Next Page Link doesn’t exists

/index.php/%year%/%monthnum%/%day%/%postname%/

Do I have to add the <?php wp_link_pages(); ?> code in my index.php file to fix this?

Thx for the help. The code of the index.php file is:

?php get_header(); ?>
<div id=”contents” class=”clearfix”>

<div id=”left_col”>
<?php $options = get_option(‘mc_options’); ?>
<?php $odd_or_even = ‘odd’; ?>
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>

<div class=”post_<?php echo $odd_or_even; ?>”>
<div class=”post clearfix”>
<div class=”post_content_wrapper”>
<h2>“><?php the_title(); ?></h2>
<div class=”post_content”>
<?php the_content(__(‘Lees verder’, ‘monochrome’)); ?>
</div>
</div>
<dl class=”post_meta”>
<dt class=”meta_date”><?php the_time(‘Y’) ?></dt>
<dd class=”post_date”><?php the_time(‘d’) ?><span>/<?php the_time(‘m’) ?></span></dd>
<?php if ($options[‘author’]) : ?>
<dt><?php _e(‘POSTED BY’,’monochrome’); ?></dt>
<dd><?php the_author_posts_link(); ?></dd>
<?php endif; ?>
<dt><?php _e(‘CATEGORY’,’monochrome’); ?></dt>
<dd><?php the_category(‘
‘); ?></dd>
<?php if ($options[‘tag’]) : ?>
<?php the_tags(__(‘<dt>TAGS</dt><dd>’,’monochrome’),’
‘,'</dd>’); ?>
<?php endif; ?>
<dt class=”meta_comment”><?php comments_popup_link(__(‘Plaats reactie’, ‘monochrome’), __(‘1 Reactie’, ‘monochrome’), __(‘% Reacties’, ‘monochrome’)); ?></dt>
<?php edit_post_link(__(‘[ EDIT ]’, ‘monochrome’), ‘<dd>’, ‘</dd>’ ); ?>
</dl>
</div>
</div>

<?php $odd_or_even = (‘odd’==$odd_or_even) ? ‘even’ : ‘odd’; ?>
<?php endwhile; else: ?>
<div class=”post_odd”>
<div class=”post clearfix”>
<div class=”post_content_wrapper”>
<?php _e(“Sorry, but you are looking for something that isn’t here.”,”monochrome”); ?>
</div>
<div class=”post_meta”>
</div>
</div>
</div>
<?php endif; ?>

<div class=”content_noside”>
<?php include(‘navigation.php’); ?>
</div>

</div><!– #left_col end –>

<?php get_sidebar(); ?>

</div><!– #contents end –>

<div id=”footer”>
<?php get_footer(); ?>

Does anybody got a suggestion what I have to do with get_pagenum_link()?
As ryans149 said, I got an error an navigation.php on line 4.

This is the code of the navigation.php:

<?php

global $wp_rewrite;
$paginate_base = get_pagenum_link(1);
if (strpos($paginate_base, '?') || ! $wp_rewrite->using_permalinks()) {
	$paginate_format = '';
	$paginate_base = add_query_arg('paged', '%#%');
} else {
	$paginate_format = (substr($paginate_base, -1 ,1) == '/' ? '' : '/') .
	user_trailingslashit('page/%#%/', 'paged');;
	$paginate_base .= '%_%';
}

echo '<div class="page_navi clearfix">'. "\n";
echo paginate_links( array(
	'base' => $paginate_base,
	'format' => $paginate_format,
	'total' => $wp_query->max_num_pages,
	'mid_size' => 2,
	'current' => ($paged ? $paged : 1),
        'type' => 'list',
        'prev_text' => '&laquo;',
        'next_text' => '&raquo;',
));
echo "\n</div>\n";

?>
