Older entries link not working anymore

Hello!

The Older entries link at the bottom of my home page is now in a loop, bringing me to page 2 but displaying the same posts as page 1. Also, the older entries link on page 2 directs to page 2 when it should be page 3.

Here’s the code on my .php page

global $wp_query, $suffusion_unified_options, $page_of_posts;
foreach ($suffusion_unified_options as $id => $value) {
	$$id = $value;
}
$page_of_posts = true;

get_header();

$paged = get_query_var('paged');
if (!isset($paged) || empty($paged)) {
	$paged = 1;
}
//$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;

$category_exclusive = get_post_meta($posts[0]->ID, 'category', true );

if( $category_exclusive )
{
$cat = get_cat_ID($category_exclusive);
$args = array(
	'category__in' => array( $cat ),
	'orderby' => 'date',
	'order' => 'DESC',
	'paged' => $paged,
);
}
else
{
$args = array(
	'orderby' => 'date',
	'order' => 'DESC',
	'paged' => $paged,
);
}
$temp = $wp_query;  // assign original query to temp variable for later use
//$wp_query = null; // Resetting this to null was causing a PHP Notice to pop up
$wp_query = new WP_Query($args);

suffusion_query_posts();
?>

website is https://www.fredericsanchez.com

It only does it on this particuliar page, not the others.

Any idea what’s wrong ? Thanks a lot.
