solved by myself.
So, need to find public function mark_title in mark-new-posts.php (line 194)
Change to:
public function mark_title($title, $post_id = null) {
if (in_the_loop() || is_admin() || !$this->is_new_post($post_id)) return $title;
return $this->options->check_markup ? '{mnp_mark}' . $title . '{/mnp_mark}' : $this->wrap_title($title);
}
to show in sidebar only or
public function mark_title($title, $post_id = null) {
if (is_admin() || !$this->is_new_post($post_id)) return $title;
return $this->options->check_markup ? '{mnp_mark}' . $title . '{/mnp_mark}' : $this->wrap_title($title);
}
to modify titles everywhere, except wp-admin panel.
