Edited file: send-mail.php
section: // send mail
Added after all headers
$headers .= “MIME-Version: 1.0″.”\r\n” .”Content-type: text/plain; charset=UTF-8″. “\r\n”;

changed string
$mail_result = mail( $to, $subject, $body, $headers );
to string
$mail_result = mail( $to, ‘=?UTF-8?B?’.base64_encode($subject).’?=’, $body, $headers );

now everything is ok
