I've been trying to build an archive index (see http://www.openwin.org/mike/archive.php)
So far so good, the monthly list all works, and the category list looks right, but all links are broken.
That all look like this:
As you can see, the name of the category itself is missing.
If you strip all the HTML and just look at the PHP tags, you have this:
<?php wp_get_archives('type=monthly&show_post_count=true&format=other&after=<br>'); ?>
<?php wp_list_cats('all&optioncount=1&list=0'); ?>
