Pages not working in custom-post-type/taxonomy-slug case

Hello there,

I’m using this plugin to make taxonomy and custom post type everything works fine except one thing.

custom-post-type/taxonomy-slug case lead me to 404 pages and I dont understand why.

I’ve notice there is a page parameter in custom post type rewrite options but it is set to true and it does not work.

I’m really anoyed by this thing.

Here are my settings :

custom post type slug : jeu/%jeux%
taxonomy slug : jeu

To replace %jeux% in URL i’m using this in function file

function wpa_show_permalinks( $post_link, $id = 0 ){
    $post = get_post($id);
    if ( is_object( $post ) && $post->post_type == 'jeu' ){
        $terms = wp_get_object_terms( $post->ID, 'jeux' );
        if( $terms ){
            return str_replace( '%jeux%' , $terms[0]->slug , $post_link );
        } else {
            return str_replace( '%jeux%' , 'autres' , $post_link );
        }
    }
    return $post_link;
}
add_filter( 'post_type_link', 'wpa_show_permalinks', 1, 2 );

Admin, can you please help me here ? I’ve tried everything that I can think of !
