WordPress import not importing custom taxonomy

Not really, the sites were just built at different times. Do you think it will make a difference? Thanks.

The posts I’m trying to import are just one custom post type. The site has other post types with lots of content (and a few plugins) so I’m not ready to undertake an update at this point. Especially if I’m not sure it will solve my import issue.

I’m at a loss here, I “downgraded” my 3.3.2 version to 3.2.1 and exported so I was doing an export/import from the same version of WP. Still no luck, I get the custom posts but no custom taxonomy or fields.

Just to clarify I’m doing an “All content” export to ensure I get all relevant info in my export file.

Just in case I’m missing something, here are the relevant bits from my export blog’s functions.php file (post/taxonomy only, the custom fields I’ll leave out for now):

function build_taxonomies() {
    register_taxonomy(
	'site_archives_cats',
	'site_archives',
	array(
		'hierarchical' => true,
		'label' => 'Categories',
		'query_var' => true,
		'rewrite' => true
	)
);
	register_taxonomy(
	'site_archives_tags',
	'site_archives',
	array(
		'hierarchical' => false,
		'label' => 'Tags',
		'query_var' => true,
		'rewrite' => true
	)
);
}
add_action( 'init', 'build_taxonomies', 0 ); 

function create_my_post_types() {
	register_post_type( 'site_archives',
		array(
			'labels' => array(
				'name' => __( 'Archives' ),
				'singular_name' => __( 'Archives' )
			),
			'public' => true,
			'show_ui' => true,
			'publicly_queryable' => true,
			'exclude_from_search' => false,
			'menu_position' => 5,
			'supports' => array( 'title', 'editor', 'excerpt', 'revisions'),
			'taxonomies' => array( 'site_archives_cats', 'site_archives_tags'),
			'has_archive' => 'article-archives',
			'register_meta_box_cb' => 'add_additional_info_meta',
			'rewrite' => array('slug' => 'archives')
		)
	);
}
add_action( 'init', 'create_my_post_types' );

And my import blog’s functions.php is an exact copy/paste.

Any ideas at all on why the custom taxonomy is not being imported? I feel like it must be something painfully simple, but I just don’t get it.

Thanks.
