Question

In my index.php I use this code to limit the posts per page and it works without any problems:

$showposts = 5;
$do_not_show_stickies = 1;
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$args = array('category__in' => $cat, 'showposts' => $showposts, 'ignore_sticky_posts' => 1, 'paged' => $paged);

$loop2query = new WP_Query($args);

query_posts($args); if(have_posts()) : while (have_posts()) : the_post(); ?>

<div class="blogpost"> ... </div>

<?php endwhile; endif;
posts_nav_link(); // Navigating the pages with $showposts each. ?>

The same code did not work in category.php so I changed it to the following but it still does not work:

$showposts = 4;
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;

if (have_posts()) { while (have_posts()) { the_post(); ?>
    <div class="blogpost"> ... </div>

<?php } }

else { ?>
    <p>There are no blog posts in this category.</p>
<?php } ?>

<?php posts_nav_link(); // Navigating the pages with $showposts each. ?>

I tried to change the line with if(have_posts()) : while (have_posts()) : the_post(); ?> [...] in category.php to make it similar to that line in index.php but nothing I tried worked.

WordPress has a setting for this, found in the admin area under SETTINGS -> READING -> Blog pages show at most

You can use this instead of custom-modifying your queries. It may make it a little easier to maintain your project down the road.
