When scrolling on my demo home page, when you get to the end of posts, I see this error popping up in my dev console:
http://client.kathyisawesome.com/page/4/ 404 (Not Found)
In theory there shouldn't be a "previous posts" link.. and in fact my code for that link is wrapped in a conditional
<?php if ( get_previous_posts_link() ) : ?> <div class="nav-next"><?php previous_posts_link( __( 'Newer posts <span class="meta-nav">></span>', 'lifelounge' ) ); ?></div> <?php endif; ?>
SO when it no longer finds that link, shouldn't it stopped trying to scroll?
