Elegant Grunge: broken comment display & change of commentbox position

Hey Guys,
i’m using the elegant grunge theme, but now i rekognized, that the comment aren’t correctly displayed at my blog. Actually there should be a white textfield behind the comment, but there is just the lower part displayed. (https://www.leaundmarkus.de/wordpress/?page_id=476). I replaced already the comments.php with the original file from the theme’s author but there is no change in display.

The second problem i have is, that i want the comment box dispalyed above the comments, i tried to change the comments.php to change that but it didn’t word out.

Here the comments.php:

<?php

// Do not delete these lines
if (!empty($_SERVER['SCRIPT_FILENAME']) && 'comments.php' == basename($_SERVER['SCRIPT_FILENAME']))
	die ('Please do not load this page directly. Thanks!');

if ( ( function_exists('post_password_required') && post_password_required()) ||
     (!function_exists('post_password_required') && !empty($post->post_password) && $_COOKIE['wp-postpass_' . COOKIEHASH] != $post->post_password) ) {
    ?>
	<p class="nocomments"><?php _e('This post is password protected. Enter the password to view comments.', 'elegant-grunge') ?></p>
    <?php
	return;
}

?>

<?php
function elegant_grunge_comments_template($comment, $args, $depth) {
    $GLOBALS['comment'] = $comment;
    ?>
