I believe in the past, the 'exclude' (for categories) option was simply inserted into the sidebar.php page like this:
<?php wp_list_categories('title_li=&show_count=0&hierarchical=1&exclude=11') ?>
However, it doesn't work with my version of wordpress.
Just wondering if anybody knows a way to exclude a category from the sidebar, in a similiar way to this? (ie, has the syntax changed in this version, or something?)
Any help would be greatly appreciated.
