Posts por página não funcionando

Boa tarde pessoal, quando vou na opção Configurações > Leitura > As páginas do blog mostram no máximo [ ], simplesmente não acontece nada, o site sempre mostra 10, e antes de alterar o servidor de hospedagem pra um VPS funcionava normalmente.
Tentei adicionar o query_posts( $query_string . ‘&posts_per_page=1’ ); Sem sucesso. Sou novato em WP qualquer ajuda seria válida. Uma cópia do home.php pra ajudar:

<?php get_header(); ?>

<?php
$stickies = get_option('sticky_posts');
rsort($stickies);

$slideshow_cat	= arras_get_option('slideshow_cat');
$featured_cat 	= arras_get_option('featured_cat');
$news_cat 		= arras_get_option('news_cat');

$slideshow_count	= (int)arras_get_option('slideshow_count');
$featured_count 	= (int)arras_get_option('featured_count');
?>

<div id="content" class="section">
<?php arras_above_content() ?>

<?php if (!$paged) : ?>

<?php arras_above_index_featured_post() ?>

<!-- Featured Articles -->
<?php if ( $featured_cat !== '' && $featured_cat != '-1' ) : ?>
<div id="index-featured">
<?php if ( arras_get_option('featured_title') != '' ) : ?>
	<div class="home-title"><?php _e( arras_get_option('featured_title'), 'arras' ) ?></div>
<?php endif ?>
	<?php
	if ($featured_cat == '-5') {
		if (count($stickies) > 0) {
			$query2 = array('post__in' => $stickies, 'showposts' => $featured_count );
			if ( arras_get_option('slideshow_cat') == $featured_cat ) {
				$query2['offset'] = $slideshow_count;
			}
		}
	} else {
		if ($featured_cat == '0') {
			$query2 = 'showposts=' . $featured_count;
		} else {
			$query2 = 'showposts=' . $featured_count . '&cat=' . $featured_cat;
		}

		if ( $slideshow_cat == $featured_cat ) {
			$query2 .= '&offset=' . $slideshow_count;
		}
	}

	arras_render_posts( apply_filters('arras_featured_query', $query2), arras_get_option('featured_display'), 'featured' );
	?>
</div><!-- #index-featured -->
<?php endif; ?>

<?php arras_above_index_news_post() ?>

<!-- News Articles -->
<div id="index-news">

	'showposts' => ( (arras_get_option('index_count') == 0 ? get_option('posts_per_page') : arras_get_option('index_count')) ),
	'caller_get_posts' => 1

$news_offset = 0;
if ($slideshow_cat == $news_cat) {
	$news_offset += $slideshow_count;

}
$news_query_args['offset'] = $news_offset;

query_posts( apply_filters('arras_news_query', $news_query_args) );
arras_render_posts(null, arras_get_option('news_display'), 'news'); ?>
