Having a weird problem on a site where the 'previous posts' at the bottom of a category template is only working on first click.
i.e. domain.com/news - click 'previous posts' - loads the next 20 posts on domain.com/news/page/2
However once on /page/2, when I click 'previous posts' again it loads /page/3 but just says 'Sorry, no posts matched your criteria.' There are definitely more posts as extending the query to display unlimited posts reveals them.
This is whats being used:
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1; query_posts('order=DESC&orderby=date&category_name=news, film-projects, our-projects&posts_per_page=20&paged='.$paged);
and at the bottom of the page:
<?php next_posts_link('« Previous Entries') ?> <?php previous_posts_link('Next Entries »') ?>
