The solution described above didn’t work for a website I developed: https://www.anacarmen.com
Some small changes were necessary if you used the blog.php as described in https://codex.www.ads-software.com/Pages
Instead of index.php, I used blog.php in the .htaccess file.
RewriteRule ^(blog)/page/?([0-9]{1,})/?$ /blog.php?pagename=$1&pgd=$2 [QSA,L]
RewriteRule ^(blog)(/[0-9]+)?/?$ /blog.php?pagename=$1&pgd=$2 [QSA,L]
And I replaced the original code in blog.php with
<?php $qy = preg_replace('/page_id=d*&?/','',$_SERVER['QUERY_STRING']); ?>
<?php $qy = preg_replace('/pagename=w*&?/','',$qy); ?>
<?php $qy = preg_replace('/page=w*&?/','',$qy); ?>
<?php $qy = preg_replace('/pgd=(d*)(&?)/','paged=${1}${2}',$qy); ?>
<?php $qy = $qy==''?'orderby=date':$qy; ?>
<?php query_posts($qy);
extract ($wp_query->query_vars);
load_template( TEMPLATEPATH . '/index.php'); //loads index
?>
