error in komento

Hello,


I'm two problems with Komento. Can you help me?

1) on the frontpage page is showing this:

Invalid template file /home/u599892214/public_html/components/com_komento/themes/kuro/comment/bar.php;

2) when I try to post a comment on a easyblog posting , the screen dims and a message " ok" in red. The button "submit comment " becomes "error";

What can I do?

Thanks!!
