		}
	}
}

Setelah itu include file di bawah ini:

<div class="navigation">
       <?php wp_pagenavi(); ?>
</div>

ke dalam file index, dan search sesudah syntax berikut:

<?php endwhile; ?>

Selanjutnya include syntax di bawah ini ke dalam style.css

/*========= TOP NAVIGATION =========*/

/*- Navigation -*/
.navigation {
	clear: both;
	padding: 5px 40px 5px 12px;
}
.wp-pagenavi a {
	padding: 2px 4px;
	margin: 1px;
	_margin: 1px;
	text-decoration: none;
	border: 1px solid #000000;
	color: #000000;
	background-color: #fff;
}

.wp-pagenavi a:hover {
	border: 1px solid #e8a02c;
	color: #e8a02c;
}

.wp-pagenavi span.pages, .wp-pagenavi span.current, .wp-pagenavi span.extend {
	padding: 2px 4px;
	_padding: 2px 0;
	margin: 1px;
	_margin: 1px;
	border: 1px solid #000;
	color: #000;
	background-color: #fff;
}

mainkan CSSnya sesuka Kamu..

Semoga membantu
