Hello.
This works for all pages and posts. However, it does not work for archived posts that go beyond the first page.
For example, the NEXT PAGE link at the bottom of the posts looks like:
https://websiteurl.com.php.phppage/2.php
Thus, all posts beyond the first page of posts cannot be found.
Here is the code in question:
———-> (index.php)
<?php posts_nav_link(‘ — ‘, __(‘« Previous Page’), __(‘Next Page »’)); ?>
