By default, WordPress has functions to display links to previous and next pages. This is better than nothing, but I don’t understand why the folks at WordPress don’t build a pagenevi by default. But here is a plugin to display page numbers.

Configuration:

1. First of all download Pagenavi WordPress Plugin.
2. Unzip the archive and put the wp-pagenavi folder into your plugins folder (/wp-content/plugins/).
3. Activate the plugin from the Plugins menu.
4. Open the file that you want the pagination to be displayed in (e.g. index.php, categories.php, search.php, etc.), and find the following code:

<div>
<div><?php next_posts_link('Previous entries') ?></div>
<div><?php previous_posts_link('Next entries') ?></div>
</div>

Replace Code With.
<?php
include('wp-pagenavi.php');
if(function_exists('wp_pagenavi')) { wp_pagenavi(); }
?>
Save all pages. Refresh page.
