Please..anyone? I am getting a heart attack … what can I do in order to get back to my admin dashboard? Shuld I delete the entire child theme folder? Should I delete functions.php in twenty twelve?
(Yes, i know, it was extremly stupid to copy the entire functions.php from twenty twelve to the child theme. Yes, I will create a new theme, basic, from scratch, without any fancy functions).
BUT – What can I do now?

Ok, I have code capable of doing this, but I don’t know how to limit the comments to a category, and if I am using this code in two instances it might be a heavy load on the server. Here is the code (so far):

<?php>

$sqlstr = '';
$blog_list = get_blog_list( 0, 'all' );
$sqlstr = "SELECT 1 as blog_id, comment_date, comment_id, comment_post_id, comment_content, comment_date_gmt, comment_author, comment_author_email from ".$table_prefix ."comments where comment_approved = 1 ";
$uni = '';
foreach ($blog_list AS $blog) {
    $uni = ' union ';
    $sqlstr .= $uni . " SELECT ".$blog['blog_id']." as blog_id, comment_date, comment_id, comment_post_id, comment_content, comment_date_gmt, comment_author, comment_author_email   from ".$table_prefix .$blog['blog_id']."_comments where comment_approved = 1 ";
}
$limit = '20';
$limit = ' LIMIT 0, '. (int)$wgt_count;
$sqlstr .= " ORDER BY comment_date_gmt desc " . $limit;
$comm_list = $wpdb->get_results($sqlstr, ARRAY_A);
?>

<!--the output before styling-->

<ul>
<?php
$count = 0;
foreach((array)$comm_list as $comment):
  $count++;
  if($count == $number+1) break;
  ?>
  <li>
   <?php echo get_avatar($comment->comment_author_email, 32); ?>
   <a href="<?php echo get_blog_permalink($comment->blog_id, $comment->comment_post_ID); ?>" title="commented on <?php echo strip_tags($comment->post_title); ?>">
   <?php echo $comment->comment_author; ?> wrote:
   <?php echo convert_smilies(wp_trim_excerpt($comment->comment_content)); ?>
   (<?php echo human_time_diff(strtotime("{$comment->comment_date_gmt}")); ?>)
   </a>
  </li>
<?php
endforeach;
?>
</ul>

I am using 3.4.2. Perhaps it is the wp version, then. And soon we have 3.5! Please, developer: something is wrong.

Ah … ops. I tried to ask for posts from two categories (IDs), but when I removed these, the output came … Strange, since this is the only two categories with content.
