Comments are no longer printet on pages

This theme from 2011 looks already nice today, but there are some code issues printing the comments down below a page. The comments counter shows comments but the theme don’ t list them any more.
Replace following lines in /DCROOT/wp-content/themes/gray-opaque/comments.php

wp_list_comments(array(
‘type’ => ‘comment’,
‘callback’ => ‘greyopaque_comment’
));

with

wp_list_comments(array(
‘type’ => ‘comment’,
// ‘callback’ => ‘greyopaque_comment’
‘avatar_size’ => 60,
‘style’ => ‘ol’,
‘short_ping’ => true,
));

Correct comment date position:
replace the following lines in /DCROOT/wp-content/themes/gray-opaque/styles.css

.comment-meta {font-size:12px; float:right;}

with

.comment-meta {font-size:12px;position:absolute;top:20px;right:0px;}

or

.comment-meta {font-size:12px;}
