Custom Text for Post Category

Hi Samsa17,
We have a filter hook available that you can use, but you’ve to know the coding. Please try to copy my below code and paste it under your Theme functions file(please paste the end of the file).
To navigate the function file, go to Apperace => Theme File Editor and from the right sidebar, select Theme Functions.

(Feel free to customize the link and title value on my code)

Code to copy:

function breadcrumb_items_array($items){
    $items[1] = array (
        'link' => 'http://myCustomBradcrumb.com',
        'title' => 'My Custom Breadcrumb',
    );

    $items[2] = array (
        'link' => 'http://myCategoryUrl.com',
        'title' => 'My Custom Category',
    );

    return $items;
}
add_filter('breadcrumb_items_array', 'breadcrumb_items_array');

Expected preview: https://i.imgur.com/Ztqxuia.png
