I am just trying to find out, why the Tags do not work as supposed to inside this template. I will post the archive.php and functions.php code, so somebody can hopefully point me into the right direction to make Tags work.

archive.php code:

<?php

$oCategory = get_queried_object();
$bReport = in_array($oCategory->term_id, nr_get_report_category_ids());

if ($bReport) {
    $aCategories = nr_get_report_categories();
    $aCategoryIDs = nr_get_report_category_ids();
} else {
    $aCategories = nr_get_news_categories();
    $aCategoryIDs = nr_get_news_category_ids();
}

$aArgs = array(
     'nopaging' => true
    ,'category' => $oCategory->term_id
);
$aPosts = get_posts($aArgs);
$aLatestPosts = get_posts(array(
    'category' => implode(',', $aCategoryIDs)
));
global $aPaginatorData;
list($aPosts, $aPaginatorData) = nat_calculate_pagination($aPosts, 10);

get_header();

?>
