@ryanck: I strongly recommend against modifying any of the files distributed by Breadcrumb NavXT. Your changes will be overwritten when you update Breadcrumb NavXT. Instead, you should use the bcn_breadcrumb_url filter to remove the category link. For example, the following placed in a site specific plugin should achieve the same result without modifying the plugin:

add_filter('bcn_breadcrumb_url', 'my_breadcrumb_url_changer', 3, 10);
function my_breadcrumb_url_changer($url, $type, $id)
{
    if(in_array('category', $type))
    {
        $url = str_replace("category/", "", $url);
    }
    return $url;
}

The main problem with this plugin is that generally people want breadcrumbs at the top of the main content area. In my mind it would be a nice idea for the author to create an option to set automatic to the top of the main content area without any coding. That could be disabled, if someone would like to define the breadcrumbs himself.

While this would be nice to do, unfortunately, it is much easier said than done. The closest thing to a standard for themes regarding this is implementing the Theme Hook Alliance tha_breadcrumb_navigation filter. Of course, I am not aware of any themes that support this filter (though Breadcrumb NavXT does implement a hook for it). Without theme authors designing for a breadcrumb trail in their theme, there is not a way to automatically integrate the breadcrumb trail in an acceptable fashion. Sure, it is possible to throw the markup into the theme, however styling it properly so it looks correct in the them is very much specific to the theme. In the end, without theme author support, it requires user intervention to do properly.

This said, the next version of Breadcrumb NavXT (6.3) is shipping with a Gutenberg Block for breadcrumb trails. While still not a perfect solution, it provides another means of adding the breadcrumb trail to a WordPress site.

@blackandbluebird: Since this looks like it is a modsecurity rule issue, there likely isn’t much I can do on my end. I suggest analyzing your server logs (in this case modsecurity logs) to see what rule is getting tripped up. Feel free to report back what rule is getting tripped and I should be able to tell you if I can do anything. Your best options are likely to whitelist the Breadcrumb NavXT settings page for that rule, or remove that rule for the admin area. One thing to note, the default set of rules have traditionally caused issues with WordPress and you should use a set tailored for WordPress (which is what I do on my servers).

If you are getting a 404 page when saving the settings, I would check your server logs as something is not working correctly (and this sounds like a server configuration issue). As for you display issue, that is due to the styling of the theme (two of the three breadcrumbs have margin, the current item doesn’t).

Opening this support thread under the Breadcrumb NavXT Multidimension Extensions support forum probably isn’t the correct area. From what I can tell, that theme is no longer being developed, it looks like it is time to move on to a new theme (or write your own, _s or any of the twenty* themes that ship with WordPress are a good starting point). Going forward, I would use a plugin for something like maps (especially if you are entering data for points, routes, etc) rather than rely on a feature in a theme (the map plugin will probably have more users, works with multiple themes, and be supported longer than a theme from a marketplace).

I checked all of the translations with >10% completion. It looks like the following languages also have this issue:

• German
• Japanese
• Finnish
• Estonian
• Persian
• Chinese (China)
• Dutch
• Czech
• Portuguese (Portugal)
• Lithuanian
• Korean

You can write a hook into the bcn_after_fill action and remove the breadcrumb (see https://mtekk.us/archives/guides/conditionally-remove-home/ for an example for the home breadcrumb). If you don’t want to write any code, there is an extension (Breadcrumb NavXT uManager) which allows you to disallow a term/post from showing up in the breadcrumb trail.

However, if you are just doing this to keep the trail to a reasonable length, you can use CSS to shorten the individual breadcrumbs (see https://mtekk.us/archives/guides/trimming-breadcrumb-title-lengths-with-css/).
