Thanks!!! It worked perfect! =)

Here is also a code to display the category-name at the top of the page. (category.php)

<?php
  $obj = get_queried_object();
  $name = $obj->name;
?>

<?php echo $name; ?>

Sorry, one more thing =)

When you click on a category, it only shows 10 posts (in my opinion, wrong order) and no paging. =(

How can we show the full list, or show some paging?

Tanka again. =)
