Category Page – Pagination Error

    Hello and good day to everyone.

    I’m having a problem with the pagination function for my category page. Every time I click on the [Next Page] button (with the url “https://www.site.com/blog/main-category/sub-category/page/2/”), it leads me to a [page not found] page (with the url “https://www.site.com/blog/main-category/sample-page/”).

    Here’s the code that I am currently using…

    <?php get_header(); ?>

	<div class="head_content_wrapper">
		<h2 class="cat_name <?php the_title(); ?>">
		<?php
		$categories = get_categories();
			foreach($categories as $category) {
				if($category->parent == 0 ){
					echo '<a id="head_content_link" href="' . get_category_link($category) .'">' . $category->name . '</a>';
				}
			}
		?>
		</h2>
	</div>

	<section id="primary" class="site-content">
		<div id="content" role="main">

		<?php
			if ( have_posts() ) :

				query_posts( array(
				 'posts_per_page' => 3,
				 'paged'=> $paged
				));

				/* Start the Loop */
				while ( have_posts() ) : the_post();

					get_template_part( 'content', get_post_format() );

				endwhile;

			endif;

		?>

		<!-- Pagination -->
    <table width="100%" border="0" cellspacing="3" cellpadding="3">
      <tr>
        <td align="left"><?php previous_posts_link('? Previous Page') ?></td>
        <td align="right"><?php next_posts_link('Next Page ?','') ?></td>
      </tr>
    </table>
		<!--end Pagination-->

		</div><!-- #content -->
	</section><!-- #primary -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>

    Any help would be greatly appreciated. Thanks.

    Edit: I’ve tried changing the [Setting > Reading > Blog pages show at most] to 3 and 2 and 1, and it still doesn’t solve my problem. :/

    1) Change Permalinks to DEFAULT

    2) TYPE IN https://www.test.com/blog/?cat=1

    See what happens.

    I am yet to try your suggestion, but well, we have one site (actually, 5 sites) wherein the static page is set to [Your latest posts]. We set it to display only 3 posts at max, and the pagination there works without problems.

    https://www.test.com/blog/author1blog/

    https://www.test.com/blog/author1blog/page/2/

    I no longer am sure why that site’s pagination works while the others don’t. Is it perhaps that we’ve set the static page of other sites not being [Your latest posts]? But then again, these five sites currently don’t have a category list in the sidebar (if clicked, will go to the category page), so the pagination may or may not be broken.

    Okay, so I tried your suggestion… I set the max post display to 2 for testing purposes.

    cat=1 was an Uncategorized page, so no posts were displayed there.
    I went to here instead…

    https://www.test.com/blog/?cat=2

    Two posts were displayed, as well as the pagination, but when I go to the next (or previous) page…

    https://www.test.com/blog/?cat=2&paged=2

    It gave me a ‘page not found’ error. :/

    This is good!

    It’s NOT permalinks ?? We can toss that theory aside.

    The next step is to make a single install somewhere for testing this theme.

    I do not think that I can create a single WP installation though (that is the opposite of MU WP, right?), because all of the data are on our client’s computer. :/

    Dude, really? Two posts same problem.

    Closing that one.

    Sure you can. You download THEIR data and install it locally with MAMP or WAMP or VVV. That’s what developers do ??

    I am not sure if you are aware, but this thread is about my problem for creating pagination in my category page, whereas the other thread (the one you closed) was about my problem for my custom archive page being unable to get the posts from the previous year. Please reconsider reopening that thread as my archive problem is yet to be solved.

    Sure you can. You download THEIR data and install it locally with MAMP or WAMP or VVV. That’s what developers do ??

    I will see if I can.

    Or at least, open it again so I can mark it as resolved after posting my solution. I figured the problem out and wish to post how I did it there for future reference.

    I believe I already had a single WP installed in my PC. I’ll be downloading their theme now and see if the pagination works or not. Thanks!

    It’s kind of all the same issue. Your server, your theme, lots of weird pagination/permalink errors. None of which I feel are actually Multisite, to be honest, but I’m not sure and I’m not super awesome with themes. Also I can’t see your theme code.

    All this said, I reopened the other topic.

    Test locally. (Oh and you can too, easily, make a post in 2012 and test if those archives work too. That’s why you always want a local site ?? Test stuff without annoying customers.)

    Apologies for the late reply. My office isn’t open during the weekends.

    Anyway, I have tried what you suggested: creating a replica of the site on my local PC (but only a single WP installation, not MU). I tried creating three test posts, and only displaying one post at a time, but unfortunately, when I click on the [Next] page, it throws me back to the homepage.

    So I suppose there is something wrong with the theme we are using.

    Also, what do you mean by [theme code]?

    Theme code… You know, all the files that are in your theme’s folder? The code?

    And yes, this heavily implies you have bad code. You’ll have to make it all public somewhere like github and post in the theme section for help there. It’s not Multisite, though, which is good.

    I’m just going to post here, and mark this problem of mine as resolved. We found out a solution to this annoying pagination problem of ours: the permalink.
    Before, we were using this…
    /%category%/%post_id%/
    …but we changed it to this…
    /%author%/%post_id%/
    and the pagination started working.

    I never would have realized that it was an author page all along. One disadvantage of taking over a project that I didn’t start with. :/

    Anyway, apologies for the trouble, and thanks for your patience and help, Ipstenu!

    You are getting a wrong pagination because you’re modifying the query in the wrong place.
    To modify the category/archive query you should do it using the ‘pre_get_posts’ action and setting the query args there.

    in functions.php add:

    function m_pre_get_posts( $query ) {
    if (!is_admin() && !$query->is_main_query && is_category()) {
        $query->set( 'posts_per_page', 2 );
    } else {
        return $query;
    }
}
add_action( 'pre_get_posts', 'm_pre_get_posts' );

    And in if the page is still redirecting to 404, you should check the default posts per page number set in the backend under Settings/Reading -> Blog pages show at most
    By default it’s set to 10, and if you query posts with a number less than the default post per page number the page breaks and redirects to 404. Decrease the Blog pages show at most number and your page will work.

    I have a problem with category pagination:

    I put this code in functions.php

    function pagenavi( $p = 2 ) { // pages will be show before and after current page
  if ( is_singular() ) return; // don't show in single page
  global $wp_query, $paged;
  $max_page = $wp_query->max_num_pages;
  if ( $max_page == 1 ) return; // don't show when only one page
  if ( empty( $paged ) ) $paged = 1;
  // echo '<span class="pages">Page: ' . $paged . ' of ' . $max_page . ' </span> '; // pages
  if ( $paged > $p + 1 ) p_link( 1, 'First' );
  if ( $paged > $p + 2 ) echo '... ';
  for( $i = $paged - $p; $i <= $paged + $p; $i++ ) { // Middle pages
    if ( $i > 0 && $i <= $max_page ) $i == $paged ? print "<span class='page-numbers current'>{$i}</span> " : p_link( $i );
  }
  if ( $paged < $max_page - $p - 1 ) echo '... ';
  if ( $paged < $max_page - $p ) p_link( $max_page, 'Last' );
}
function p_link( $i, $title = '' ) {
  if ( $title == '' ) $title = "Page {$i}";
  echo "<a class='page-numbers' href='", esc_html( get_pagenum_link( $i ) ), "' title='{$title}'>{$i}</a> ";
}

    And then i put this in index.php

    <?php pagenavi(); ?>

    All is right but the only thing is the category pagination.
    For example in the “Development” category, right now, you can enter and see the all of posts, that’s because i set the “Reading Settings” in 5 (I have just 5 posts) but when i put 3 for example, is horrible, the quote “Older Post” appear and the sidebar is in the footer and distorting.

    Plis helpme!
