Wordpress 3.1 problem, getting 404

Question

Today morning I updated my wordpress, everything was fine, but suddenly I came to know that if I click on any post which is not having custom taxonomies selected in it, are giving me 404 pages.

I thought this is due to some plugins, so I deactivated all the plugins, and then I checked, everything was working, then I activated one by one plugin and came to know the actual plugin due to which I was getting 404 is GD Custom Posts And Taxonomies Tools plugin, which I was using for creating custom Taxonomies.

But my other posts were working without 404, so i dig my head more into my wordpress, and came to know that my url structure is not supporting wordpress 3.1

In my permalinks structure, I am using custom taxonomies, which was working fine till wordpress 3.0.5, My permalink structure is this /%postname%/%location%/%mba_courses%/ where location and mba_courses are my custom taxonomies,

To make this work I am using this code:

add_filter('post_link', 'location_permalink', 10, 3);
add_filter('post_type_link', 'location_permalink', 10, 3);
function location_permalink($permalink, $post_id, $leavename) {
    if (strpos($permalink, '%location%') === FALSE) return $permalink;

        // Get post
        $post = get_post($post_id);
        if (!$post) return $permalink;

        // Get taxonomy terms
        $terms = wp_get_object_terms($post->ID, 'location');    
        if (!is_wp_error($terms) && !empty($terms) && is_object($terms[0])) $taxonomy_slug = $terms[0]->slug;
        else $taxonomy_slug = 'location';

    return str_replace('%location%', $taxonomy_slug, $permalink);
}

add_filter('post_link', 'mba_courses_permalink', 10, 3);
add_filter('post_type_link', 'mba_courses_permalink', 10, 3);

function mba_courses_permalink($permalink, $post_id, $leavename) {
    if (strpos($permalink, '%mba_courses%') === FALSE) return $permalink;

        // Get post
        $post = get_post($post_id);
        if (!$post) return $permalink;

        // Get taxonomy terms
        $terms = wp_get_object_terms($post->ID, 'mba_courses'); 
        if (!is_wp_error($terms) && !empty($terms) && is_object($terms[0])) $taxonomy_slug = $terms[0]->slug;
        else $taxonomy_slug = 'mba_courses';

    return str_replace('%mba_courses%', $taxonomy_slug, $permalink);
}

How can I make this work in 3.1 or is their any feature in 3.1 where I can have custom taxonomies on my permalink?

Answer 1

Why not post it on the dev4press.com forum? They have really good support. Milan is pretty quick to respond too.

I haven't yet tried using my version of this plugin on 3.1. Just GD Press Tools.

Answer 2

For me it was the Top Level Categories plugin. Bummer too, I like that plugin. Maybe there is another one that is more up to date.
