So, for per instance/call to bcn_breadcrumb there are only a couple of unique settings available, see https://mtekk.us/code/breadcrumb-navxt/breadcrumb-navxt-doc/#Usingbcn_displayandbcn_display_list

Beyond that, the settings in the settings page are going to apply to every call to bcn_display().

For some reason your product CPT root breadcrumb title is blank. That is why Google is complaining. If you don’t want that in your breadcrumb trail, you probably want to have the “Root Page” set to –Select– and have “Archive Display” set to unchecked.

Currently, your best bet is to modify the URL using the bcn_breadcrumb_url filter.

From the Breadcrumb NavXT side, I should probably revisit the code that is adding that query arg and make sure there isn’t a better way of doing it (which would tie into the rewrite system so it would just ‘know’ you have a post_type rewrite in your permalink structure).

For the first thing you want to do, that’s known as “removing the current item”. There are several ways of doing this, see the Breadcrumb NavXT FAQ

For the second and third things you want to do, those are styling things, which will require you to add some CSS (for the time being, eventually the breadcrumb trail block will have some styling options available). Using text-decoration: none; when targeting the a element within the breadcrumb trail will remove the underlines. A grey shadow will require box shadow or drop shadow (see https://css-tricks.com/breaking-css-box-shadow-vs-drop-shadow/).

This looks problematic:

unset( $wp->query_vars['s'] );

as does this:

$query->set('s', '');

Not sure why either are being done, but either could cause the issue you’re experiencing (integer/id searches don’t show up in the breadcrumb trail).

Adding custom breadcrumbs to the breadcrumb trail can be achieved using the bcn_after_fill action. Or, using the Menu Magic extension plugin (premium).

Changing the title that is used in the breadcrumb trail can be accomplished using the bcn_breadcrumb_title filter, or Title Trixx (uses term/post meta boxes) or Menu Magic (uses menu entry titles) extension plugins.

For the hidden category thing, if you want to always exclude category 1, you can either remove it using bcn_after_fill, use a custom taxonomy instead for category 1 (hidden categories typically mean you want something extra to organize by but don’t want to show which usually is better suited for a custom taxonomy but not always), or if you leave it out of the hierarchy in menu for Menu Magic, it should be left out of the trail. That said, if you have many categories you wish to do this with, the menu you will have to setup may be a bit cumbersome.

Lastly, normally, for pages, tag archives, 404 pages, etc where you don’t want the breadcrumb trail appear you’d use theme templates to control that (general philosophy is where and when the breadcrumb trail is displayed is the role of the theme, what the breadcrumb trail displays is the role of the plugin)

Thanks for reporting this. Looking into this, it appears the problem is boolean settings are not handled properly when importing. Since the exporter only exports what is save in the database and as of 7.0, Breadcrumb NavXT has moved to only saving the non-default setting values, the export file does not contain boolean settings that have the default value of ‘true’. I’m tracking this with the following github issue: https://github.com/mtekk/Breadcrumb-NavXT/issues/289

How are you calling the breadcrumb trail? The linked page has <li> tags that probably shouldn’t be there. That said, I’m not sure how with Breadcrumb NavXT you would get <li> tags without extra stuff in them (using bcn_display_list() is going to add other things within the <li> tags), unless prevented using the bcn_display_attributes filter.
