In general, after installing and activating the plugin, you will still need to call the breadcrumb trail. Your options are using the built-in widget, the built-in gutenberg block, or calling bcn_display() within your theme. Looking at the linked site, it appears you may have already discovered this. Are you still experiencing a problem displaying the breadcrumb trail?

Is the taxonomy a hierarchical or non-hierarchical taxonomy? Based on the terms you listed, I assume it’s a hierarchical taxonomy. If that is the case, you can use the bcn_pick_post_term filter to force a different term to be picked when term id=3 is set.

add_filter('bcn_pick_post_term', 'my_bcn_term_filter', 3, 10);
function my_bcn_term_filter($term, $post_id, $post_type, $term_taxonomy)
{
if($term->term_id === 3)
{
$term = get_term($term->parent, $term->taxonomy);
}
return $term;
}

The above example assumes the term you don’t want to use has the term_id of 3, and you wanted to use its parent instead. This can be modified for other term selection behaviors depending on exactly what behavior you want.

Assuming what you copied and pasted in the comment is what you are seeing, the problem is the & gt;. As to how that is appearing, I can think of a couple of ways. The first is that wherever you copied the calling code from and then pasted into tried to “help” you and tried turning something into an HTML entity instead of the raw characters. This could be due to either a text editor doing something goofy (the built in WordPress plugin/theme/code editor could potentially do this) or if you are using a plugin that lets you execute PHP wherever you want rather than editing a .php file.

Normally, when you get a 403 error, the issue usually a WAF, such as ModSecurity not liking the post request. I recommend checking your web server’s access and error logs to see if this is the case (usually ModSecurity will say in the error log what rule you tripped).

Thanks for trying Breadcrumb NavXT on PHP8. Another user had previously reported this warning (see https://wordpress.org/support/topic/php-8-0-compatibility-2/) and the issue will be fixed in the next release (will likely be released sometime in April).

For the built-in Post post type, the root page/archive is controlled by the “Your homepage displays” setting under Settings > Reading. You need to have a “Posts page” set. At that point, the breadcrumb for the Post post type archive will be added to the breadcrumb trail.

On the WooCommerce pages, is there any evidence in the generated markup that the extras.php is being used (e.g. is the breadcrumbs div there)? It’s possible that there are WooCommerce specific theme files (either for the theme itself or in your child theme) that for one reason or another don’t pull in extras.php for the header.

How are you currently calling the breadcrumb trail? Typically, a call to bcn_display() is added to the the appropriate theme file. Alternatively, the call to bcn_display() could be used within a wrapper function (so that you can add the proper wrapping HTML tags). If that’s how it already is being called, all you have to do add that function to the genesis_after_entry action. You’ll need to add that custom code to a small, site specific plugin (quite simple, and the best place for many of these small code snippits instead of your theme’s functions.php).
