    function sgr_show_current_cat_on_single($output) {
global $post;
if( is_single() ) {
$categories = wp_get_post_categories($post->ID);
foreach( $categories as $catid ) {
$cat = get_category($catid);
// Find cat-item-ID in the string
if(preg_match('#cat-item-' . $cat->cat_ID . '#', $output)) {
$output = str_replace('cat-item-'.$cat->cat_ID, 'cat-item-'.$cat->cat_ID . ' current-cat', $output);
}
}
}
return $output;
