Dear kumodiva
Please open modules\mod_yt_k2ajax_tabs\assets\libs-ajax.php file, find this code:
if ($this->sort_order_field == 'random') {
$query .= ' ORDER BY rand()';
} else {
$query .= ' ORDER BY ' . $this->sort_order_field . ' ' . $this->type_order;
}
and change to:
if ($this->sort_order_field == 'random') {
$query .= ' ORDER BY rand()';
} else if ($this->sort_order_field == 'created') {
$this->type_order = 'desc';
$query .= ' ORDER BY ' . $this->sort_order_field . ' ' . $this->type_order;
} else {
$query .= ' ORDER BY ' . $this->sort_order_field . ' ' . $this->type_order;
}
