I’ve a very simple index.php:

<div id="content">
  <? get_template_part('content', get_post_format()) ?>
</div>

<div id="pagination">
  <? previous_posts_link() ?>
  <? next_posts_link() ?>
</div>

And my content.php looks roughly like this:

<?
$paged = get_query_var('paged') ? get_query_var('paged') : 1;
query_posts([
  'post_type' => ['articles', 'projects', 'tips'],
  'orderby' => 'date',
  'posts_per_page' => 7,
  'paged' => $paged
]);
?>

<? while(have_posts()): the_post() ?>
  <article class="post">
    <h2><? the_title() ?></h2>
    <p><? the_excerpt() ?></p>
    <ul>
      <? foreach($categories as $cat): ?>
      <li class="category"><a href="#"><?= $cat->name ?></a></li>
      <? endforeach ?>
    </ul>
  </article>
<? endwhile ?>

There are 14 posts in total but the “next” posts is always redirecting to a 404 on /page/2 instead of showing the remaining 7 posts.

Edit: If I use a custom WP_Query instead of query_posts then the next and previous links won’t even show. https://gist.github.com/elclanrs/4782705

I’ve been trying to find a solution to this issue since yesterday. I’m aware of all the other questions similar to this one, but for my particular set-up none of the solutions I found worked, including:

• http://wordpress.org/support/topic/pagination-with-custom-post-type-listing
• http://www.rjust.com/2011/03/22/fix-previous_posts_link-and-next_posts_link-for-custom-post-types/
• Make sure that “Blog pages show at most” matches posts_per_page

I’m also aware of pre_get_posts but I would like to know what’s the problem with my current setup. Any ideas?
