[Plugin: Clean My Archives] Doesn't work in WP 3.3

Cleared that problem up but still no output.

Hmm.

Breaking it up into separate years seems to have fixed this issue, since I have 10 years of posts to account for…

Seems to be working now.

Fix it.

In your theme, you use

$args = array(
                            'category__in' => array(12,13,19,153),
                            'posts_per_page' => 10,
                            'post__not_in' => get_option('sticky_posts'),
                            'paged' => curPageURL(),
                            'caller_get_posts'=>1
                            );

replace 'caller_get_posts'=>1 by 'ignore_sticky_posts' => 1
