Support » Fixing WordPress » WordPress 3.3.1 Category/Tags 404 Problem

  • Hallo,

    I have a big problem with WP 3.3.1 Yesterday I search about 8 hours to solve the problem.

    My WordPress 3.3.1 gives a 404 on a Category or Tag. But with Problem happens only with enabled Permalinks.

    I’m using Apache 2 as Webserver.

    I’ve tested the following methods fix the problem (without success):
    – disabled all plugins
    – changed themes
    – rewrite .htaccess

    I cannot understand how to fix this issue, to reproduce the Problem just try to open a category like this:

    OR a tag like this:

    The Tag Problem is a little bit different. Sometimes WordPress redirects me to a post, and sometimes to the 404 Page.

    As I found out, wordpress does not reconize correctly the requested permalink. I’m not the only one who has this Problem with 3.3.1 – but theres no solution at this time ๐Ÿ™

    Any help would be very useful, thx

  • Yes, a big problem for me too. But it goes further.
    All of my Posts were assigned to Categories and were listed on Pages by the same names of those Categories. Now they’ve all been re-assigned to ‘Uncategorized’.
    Any attempt to re-assign Posts to their correct Categories fail (in Quick Edit or Full Editing Screen).

    I’m at a loss for what to do but I may have to roll back to 3.3

    Have you had any breakthrough’s? Anyone else?

    I had this problem until a few minutes ago – clicking on any category just gave me a ‘404’ page not found. Looking through this forum I just happened to come across an answer to a similar problem – but dated a couple of years back.

    The suggestion was that you edit a page (not a post) – any page – just change it slightly and save (‘update’) the new version of the page. I thought I might as well try it and, to be honest, I did not hold out much hope it would change anything – but suddenly my categories all worked again – no 404s!!

    So, I cannot guarantee it will work for anyone else and I do not know why it worked for me – but it’s simple to do and worth trying.

    I am using the very latest version of WordPress. I thought it was me trying out loads of different themes that had somehow messed up my categories – but it’s possible the recent upgrade caused the problem?

    snipkin – You genius. I’ve been having the same problem and was pulling my hair out. Changed my htaccess, themes, plugins and none of it worked until your solution. Many thanks!

    Humbug ๐Ÿ™
    That didn’t work for me, but thanks snip kin. I’ve tried rolling back one version. Then another, and another. No dice. I disabled all plugins, I commented out all of the custom post types in my functions file. Can’t. Work. It. Out.

    All of my posts have defaulted to ‘Uncategorized’. When I try to reallocate them, the changes are not saved. Not in the Quick Edit. Not in the Full Edit.

    Any ideas?

    Ok, so my issue turned out to be a corrupt table in my wp database: wp_term_relationships. A simple repair, took less than a second and did the trick.

    mysqlcheck repair

    Hope this helps someone.


    I have the 404 issue in WP3.4 when paginating categories (and I had it a while since WP3.1). I browsed through the web and tried several solutions but none worked.
    @rafaelxy: What do you mean with:
    “Basicly, you CANT have a PAGE and a CUSTOM POST TYPE with the same name. If you do, the permalink rewrite rules will get confused and trigger a 404.

    A very simple solution I’m using is: The page that lists the custom post types is called in plural (eg. products) and the actual post type name is in singular (eg. product). So they dont conflict and it’s all fine.”

    I am quite new to WP so what is the difference btw PAGE and CUSTOM POST TYPE? I.e whe should I check if I have your described problem?

    And .. I tried your code for the function.php with no result.

    Do I have to change anything in “category.php” as well?
    The code:

    <?php get_header(); ?>	
    $cat = get_cat_id(single_cat_title("",false));
    if ($cat == 5 or $cat == 6 or $cat == 7){
    $cat = '5,6,7';}
    $pages = (get_query_var('paged')) ? get_query_var('paged') : 1;
    if(have_posts()) : while(have_posts()) : the_post(); ?>
    		<div class="post grid_20" id="<?php the_ID(); ?>">
            <?php include 'incl/info-bar.php' ?>
            <div class="left"><?php the_post_thumbnail( 'blog-post-thumbnail' ); ?></div>
    		<div class="grid_7">
    			<h3><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>
    			$args = array(
    				'post_type' => 'attachment',
    				'numberposts' => null,
    				'post_status' => null,
    				'post_parent' => $post->ID,
    				'showposts'   => 3,
    				'offset'      => 1,
    			$attachments = get_posts($args);
    			$len = 250; //Number of words to display in excerpt
    			$newExcerpt = substr($post->post_content, 0, $len);
    			if (count($newExcerpt) > 30 or count($attachments) < 3){
    			if(strlen($newExcerpt) < strlen($post->post_content)) {
    			$newExcerpt = $newExcerpt.'... <a href="'.get_permalink().'">Lรคs mer</a>';
    			echo '<div class="entry"><p>'.$newExcerpt.'</p></div>'; //finally display excerpt
    			} else {
    			if ($attachments) {
    			echo '<div class="images left">';
    			foreach ($attachments as $attachment) {
    			echo wp_get_attachment_link($attachment->ID, 'thumbnail');
    			echo '</div>';
            <div class="comments grid_6 omega">
    		   $args = array(
    				'status' => 'approve',
    				'number' => '2',
    				'post_id' => $post->ID, // use post_id, not post_ID
    			$comments = get_comments($args); if($comments) { ?>
            <h4><?php comments_popup_link('', '1 Kommentar', '% Kommentarer'); ?></h4>
    		   foreach($comments as $comment):
               $length = 40; // adjust to needed length
               $thiscomment = $comment->comment_content;
               if ( strlen($thiscomment) > $length ) {
               $thiscomment = substr($thiscomment,0,$length);
               $thiscomment = $thiscomment .' ...';
    			<li id="comment-<?php comment_ID() ?>">
    			<div class="left"><?php echo get_avatar( get_comment_author_email(), '40' ); ?></div>
    			<p><a href="<?php the_permalink(); ?>/#comment-<?php comment_ID() ?>"><?php comment_author(); ?></a>:

            <?php } ?>
    		</div> <!-- .post -->
