Способ выше не совсем подходит, т.к если пользователь с X id пишет в тему, то там автоматически отключает CSS.
Все дело в расстановке. Т.е код:
{{if $comment->author()->member_id == X}}
Должен стоять выше всех пунктов в меню, в нашем случае до:
<li class='cAuthorPane_photo'>
{template="userPhoto" app="core" group="global" params="$comment->author(), 'large', $comment->warningRef()"}
</li>
Т.е все, что выше:
{{if $comment->author()->member_id == X}}
Будет отображать, а ниже - нет.
Но не забываем еще ставить
{{else}}
И обязательно в конце всех пунктов ставить:
{{endif}}
