After a pain free upgrade today, suddenly the page navigation for previous pages of posts and next pages of posts is gone.
This bit has always done the trick in the themes:
<div class="alignleft"><?php next_posts_link('« Previous Entries') ?></div>
<div class="alignright"><?php previous_posts_link('Next Entries »') ?></div>
But it does not seem to matter what theme I use either...they all have the missing links. Any help would be super appreciated.
