What was changed regarding building the comments?

Hi guys,

since my update to 3.4.1 my comments are broken (their style and formatting, not their functionality).

Avatars have the old “68px” setting in the img-part of the HTML code and some divs that I added between comments etc. are missing.

When I set up WordPress with version 3.2.1 I used twentyeleven, duplicated it and used this to build my own theme. I changed a lot of things in my theme folder, including comments.php and functions.php.

Example: In comments.php I added a seperator-line-graphic after <?php // You can start editing here — including this comment! ?>.

In functions.php in “twentyeleven_comment”, line 513, I changed the size of the avatar to 32, “$avatar_size = 32;” etc.

All those changes don’t show up in my blog anymore. Even if I add some text it doesn’t show up in the source of the page. It feels like if the files aren’t used anymore to build the comments-html-markup.
However, for pages like the categories or authors.php, it still works.

The problem is visible here: https://www.mimimi-productions.de/?p=467

Another thing that has changed is that before it was “One thought on …” (as it says in my comments.php in my theme folder) and now it’s “One comment on” (and I can’t find this via “find in files”).

Any help is greatly appreciated!

Cheers
