elemenope on "[Plugin: Custom Post Type UI] How to remove custom post types?"

Alright, I'm not able to save the file myself, but I believe I have pinpointed the issue.

I was able to successfully see the listing myself on my own dev site, using your settings.

However, I noticed some usage of the pre_get_posts hook in your child theme's functions.php file, and that would actually have an effect on the admin.

I recommend amending that to the following:

function add_custom_types_to_tax( $query ) {
    if ( is_admin() ) {
        retu;
    }
    if( is_tag() && empty( $query->query_vars['suppress_filters'] ) ) {

        // Get all your post types
        $post_types = array( 'post', 'portfolio' );

        $query->set( 'post_type', $post_types );
        retu $query;
    }
}
add_filter( 'pre_get_posts', 'add_custom_types_to_tax' );

Notice that I added this to the top, which prevents it from running in your WP admin area.

if ( is_admin() ) {
    retu;
}

Try it out and let me know if that fixes all the remaining issues.
