Categories gone from sidebar

Hi,

I recently realized that Categories list is missing from sidebar.
I’m using default/Kubrick theme and now on 2.5.1 but don’t remember when this happened. In sidebar.php, it seems following doesn’t work as it used to.
<?php wp_list_categories(‘show_count=1&title_li=<h2>Categories</h2>’); ?>

I can see my categories in Admin just fine, and tables seem okay – though I’m not sure. Category links work fine, <host>/category/<name> that follows postings in ‘Posted in ‘.

I don’t see any errors even with “define(’WP_DEBUG’, true);” in wp-config.php.

My blog is at http://ethar.toodull.com , sorry for Korean contents.

If you have any ideas, that’ll be helpful to me.

Cheers.
