Page 2 of categories producing 404

In fact, disabling Yoast SEO does not fix the error, as previously thought.

Disabling all plugins still causes the error.

I didn’t create by hand, the template is by Elegant Themes. I have also submitted a support forum request with them, but they have not yet been forthcoming with any help.

Unfortunately there isn’t a page-photos.php, but generally I believe all categories are loaded through page-gallery.php (there are several custom post types able to use).

The code is as follows:

<?php
/*
Template Name: Gallery Page
*/
?>
<?php the_post(); ?>

<?php
$et_ptemplate_settings = array();
$et_ptemplate_settings = maybe_unserialize( get_post_meta($post->ID,'et_ptemplate_settings',true) );

$fullwidth = isset( $et_ptemplate_settings['et_fullwidthpage'] ) ? (bool) $et_ptemplate_settings['et_fullwidthpage'] : (bool) $et_ptemplate_settings['et_fullwidthpage'];

$gallery_cats = isset( $et_ptemplate_settings['et_ptemplate_gallerycats'] ) ? $et_ptemplate_settings['et_ptemplate_gallerycats'] : array();
$et_ptemplate_gallery_perpage = isset( $et_ptemplate_settings['et_ptemplate_gallery_perpage'] ) ? $et_ptemplate_settings['et_ptemplate_gallery_perpage'] : 12;
?>

<?php get_header(); ?>

<div class="main_post">
    <span class="main_post_top"></span>
	<?php if (get_option('dailynotes_integration_single_top') <> '' && get_option('dailynotes_integrate_singletop_enable') == 'on') echo(get_option('dailynotes_integration_single_top')); ?>

    <h1><?php the_title(); ?></h1>
    <img src="<?php bloginfo('template_directory'); ?>/images/line.gif" alt="line" class="line" />
    <?php the_content(); ?>

	<div id="et_pt_gallery" class="clearfix">
		<?php $gallery_query = '';
		if ( !empty($gallery_cats) ) $gallery_query = '&cat=' . implode(",", $gallery_cats);
		else echo '<!-- gallery category is not selected -->'; ?>
		<?php query_posts("showposts=$et_ptemplate_gallery_perpage&paged=$paged" . $gallery_query); ?>
		<?php if (have_posts()) : while (have_posts()) : the_post(); ?>

			<?php $width = 207;
			$height = 136;
			$titletext = get_the_title();

			$thumbnail = get_thumbnail($width,$height,'portfolio',$titletext,$titletext,true,'Portfolio');
			$thumb = $thumbnail["thumb"]; ?>

			<div class="et_pt_gallery_entry">
				<div class="et_pt_item_image">
					<?php print_thumbnail($thumb, $thumbnail["use_timthumb"], $titletext, $width, $height, 'portfolio'); ?>
					<span class="overlay"></span>

					<a class="fancybox zoom-icon" title="<?php the_title(); ?>" rel="gallery" href="<?php echo($thumbnail['fullpath']); ?>"><?php _e('Zoom in','DailyNotes'); ?></a>

				</div> <!-- end .et_pt_item_image -->
			</div> <!-- end .et_pt_gallery_entry -->

		<?php endwhile; ?>
			<div class="page-nav clearfix">
				<?php if(function_exists('wp_pagenavi')) { wp_pagenavi(); }
				else { ?>
					 <?php include(TEMPLATEPATH . '/includes/navigation.php'); ?>
				<?php } ?>
			</div> <!-- end .entry -->
		<?php else : ?>
			<?php include(TEMPLATEPATH . '/includes/no-results.php'); ?>
		<?php endif; wp_reset_query(); ?>

	</div> <!-- end #et_pt_gallery -->

    <span class="main_post_bottom"></span>
</div> <!-- .main_post -->

<div id="footer"><?php _e('Copyright 2011 ','DailyNotes'); ?> <a href="http://www.erasofstyle.com">Eras of Style</a></div>

<?php get_footer(); ?>

There is also an includes/functions/custom_posts.php which I believe may assist with this:
