The is_single() function is not working in my theme for whatever reason.
<?php if(is_single()): ?> <?php include(TEMPLATEPATH . '/footer2.php'); ?> <?php else: ?> <?php get_footer(); ?> <?php endif; ?>
That just doesn't work... The page executes as though there were no conditions and seems to skip directly to get_footer(). (I've tested this with and without single.php.)
If I were to guess, I'd say that WordPress simply isn't classifying posts in a way that is_single() can identify.
