Pagination & 404 Error Custom Template

Hi Guys,

What’s up?

I have a little problem that I can’t fix… Maybe someone have the solution !
I made a pagination trough my functions.php which looks like this

function pagination($pages = '', $range = 4)
{
     $showitems = ($range * 2)+1;  

     global $paged;
     if(empty($paged)) $paged = 1;

     if($pages == '')
     {
         global $wp_query;
         $pages = $wp_query->max_num_pages;
         if(!$pages)
         {
             $pages = 1;
         }
     }   

     if(1 != $pages)
     {
         echo "<div class=\"pagi\"><span>Page ".$paged." of ".$pages."</span>";
         if($paged > 2 && $paged > $range+1 && $showitems < $pages) echo "<a href='".get_pagenum_link(1)."'>&laquo; First</a>";
         if($paged > 1 && $showitems < $pages) echo "<a href='".get_pagenum_link($paged - 1)."'>&lsaquo; Previous</a>";

         for ($i=1; $i <= $pages; $i++)
         {
             if (1 != $pages &&( !($i >= $paged+$range+1 || $i <= $paged-$range-1) || $pages <= $showitems ))
             {
                 echo ($paged == $i)? "<span class=\"current\">".$i."</span>":"<a href='".get_pagenum_link($i)."' class=\"inactive\">".$i."</a>";
             }
         }

         if ($paged < $pages && $showitems < $pages) echo "<a href=\"".get_pagenum_link($paged + 1)."\">Next &rsaquo;</a>";
         if ($paged < $pages-1 &&  $paged+$range-1 < $pages && $showitems < $pages) echo "<a href='".get_pagenum_link($pages)."'>Last &raquo;</a>";
         echo "</div>\n";
     }
}

To display the pagination I use this:

<?php if (function_exists("pagination")) {
	pagination($loop->max_num_pages);
} ?>

My problem is that when I want to go to the page 2 I have a 404 error…

Here is my custom template:

<?php
/*
Template Name: Offres
*/
?>

<?php get_header(); ?>

<div id="content">
	<!-- Wrapper START-->
	<div class="wrapper">
		<div class="main_content">
			<h2><span>Les offres de nos partenaires</span></h2>
			<div class="content_left">
				<section>
					<h2><?php the_title(); ?></h2>
					<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
						<ul class="list_elements">
							<?php global $wp_query; ?>

							<?php $loop = new WP_Query(array('post_type' => 'offres', 'posts_per_page' => 2, 'paged' => get_query_var('paged') ? get_query_var('paged') : 1 ) ); ?>
							<?php while ( $loop->have_posts() ) : $loop->the_post(); ?>

							<li class="clearfix"><a href="<?php the_permalink(); ?>">
								<?php the_post_thumbnail("thumbs_list"); ?>
								<h3><?php the_title(); ?></h3>
								<p><?php echo excerpt(40); ?></p>
							<p class="more"><span>+</span></p>
							</a></li>

						<?php endwhile; ?>

						<?php wp_reset_query(); ?>
						</ul>
						<?php if (function_exists("pagination")) {
						    pagination($loop->max_num_pages);
					    } ?>
						<?php endwhile; else: ?>
							<p><?php _e('Désolé, nous ne trouvons pas la page demandé'); ?></p>
							<a href="<?php bloginfo( 'url' ); ?>" class="btn"><?php _e('Retour'); ?></a>
							<div class="clear"></div>
						<?php endif; ?>
				</section>
			</div>

<?php get_sidebar(); ?>
<?php get_footer(); ?>

And my register post type:

add_action('init', 'offres_init');
function offres_init()
{
  $labels = array(
    'name' => 'Offre',
    'singular_name' => 'Offre',
    'add_new' => 'Ajouter une offre',
    'add_new_item' => 'Ajouter une nouvelle offre',
    'edit_item' => 'Modifier une offre',
    'new_item' => 'Nouvelle offre',
    'view_item' => 'Voir loffre',
    'search_items' => 'Rechercher une offre',
    'not_found' =>  'Aucune offre trouvée',
    'not_found_in_trash' => 'Aucune offre dans la poubelle',
    'parent_item_colon' => '',
    'menu_name' => 'Offres'

  );
  $args = array(
    'labels' => $labels,
    'public' => true,
    'show_ui' => true,
    'show_in_menu' => true,
    'query_var' => true,
    'rewrite' => true,
    'capability_type' => 'post',
    'hierarchical' => false,
    'menu_position' => 5,

    'supports' => array('title', 'editor', 'thumbnail', 'custom-fields')
  );
  register_post_type('offres',$args);
}

add_action( 'init', 'create_taxonomy_offres', 0 );

function create_taxonomy_offres()
{
  $labels = array(
    'name' => 'Categories',
    'singular_name' => 'Categorie',
    'search_items' =>  'Rechercher une categorie',
    'all_items' => 'Toutes les categories',
    'edit_item' => 'Editer une categorie',
    'update_item' => 'Modifier une categorie',
    'add_new_item' => 'Ajouter une categorie',
    'new_item_name' => 'Nouvelle categorie',
    'menu_name' => 'Categories'
  ); 	

  register_taxonomy('offers',array('offres'), array(
    'hierarchical' => true,
    'labels' => $labels,
    'show_ui' => true,
    'query_var' => true,
    'rewrite' => array( 'slug' => 'offers' )
  ));
}

If anyone knows it will help me a lot!

Many thanks !

Jhon
