Custom taxonomy page template not found - php

Question

How can I list all posts from a custom taxonomy category into a custom template? Below is the code.
So I`ve created a custom taxonomy like this:
register_taxonomy('miniblog_category', 'post', array(
// Hierarchical taxonomy (like categories)
'hierarchical' => true,
// This array of options controls the labels displayed in the WordPress Admin UI
'labels' => array(
'name' => _x( 'MiniBlog Categories', 'taxonomy general name' ),
'singular_name' => _x( 'MiniBlog Category', 'taxonomy singular name' ),
'search_items' => __( 'Search MiniBlog Categories' ),
'all_items' => __( 'All MiniBlog Categories' ),
'parent_item' => __( 'Parent MiniBlog Category' ),
'parent_item_colon' => __( 'Parent MiniBlog Category:' ),
'edit_item' => __( 'Edit MiniBlog Category' ),
'update_item' => __( 'Update MiniBlog Category' ),
'add_new_item' => __( 'Add New MiniBlog Category' ),
'new_item_name' => __( 'New MiniBlog Category Name' ),
'menu_name' => __( 'MiniBlog Categories' ),
),
// Control the slugs used for this taxonomy
'rewrite' => array(
'slug' => 'miniblog',
'with_front' => false,
),
));
After that I also created a custom widgets that is displayed on the author`s page (right sidebar). This widget displays all current author's categories with the post numbers (the code below):
...
$current_author_id = get_the_author_meta('ID');
$categories_by_post_no = array();
foreach (get_terms('miniblog_category') as $mbc) {
// metadata term( blogger_id )
$taxonomy_blogger_id = get_term_meta($mbc->term_id, 'blogger_id', true) ;
if ($taxonomy_blogger_id == $current_author_id) {
$arg_author_posts = array(
'post_type' => 'post',
'post_status' => 'published',
'miniblog_category' => $mbc->slug,
'numberposts' => -1,
);
$term_link = get_term_link($mbc->term_id, $mbc->slug);
$categories_by_post_no[] = array(
'name' => $mbc->name,
'post_count' => count( get_posts( $arg_author_posts ) ),
'term_link' => get_term_link($mbc),
);
}
}
if (! empty($categories_by_post_no) ) {
echo '<ul class="menu">';
foreach ($categories_by_post_no as $cbpn) {
echo "<li><a href='" . $cbpn['term_link'] . "'>$cbpn[name] ($cbpn[post_count])<a/></li>";
};
echo'</ul>';
} else {
echo '<span>No articles!</span>';
}
...
In my case the links ($cbpn['term_link']) are like this:
- miniblog/culture
- miniblog/nature
- miniblog/south-america
...
but when I click on those links I received a 404 not found error.
I tried to create in the theme folder files like this (taxonomy-miniblog.php, taxonomy-miniblog-category.php) but it doesn't work. Do I have to create files for each category, e.g. taxonomy-miniblog-culture.php, taxonomy-miniblog-nature.php ...(no way!!)?
