Do you want to replace traditional <<Previous Post and Next Post>> from your blog. Do you want to insert page numbers on your blog which point to specific page number on your blog. Do you want to put page numbers like this on your blog.
For this you have to install the WP-PageNavi plugin on your WordPress. Just install and activate this plugin and then open fotter.php page of your theme by opening theme editor page from
Appearance->Editor->footer
And insert <?php wp_pagenavi(); ?> anywhere in your fotter.php page. Now save the fotter.php page and now your blog will show page numbers 
Download WP-PageNavi Plugin
If still <<Previous Post and Next Post>> are visible then you need to replace the “previous post†and “next post†code with <?php wp_pagenavi(); ?>
