Confused about the difference between a Post and a Page on WordPress?
Posts and Pages are different; when you write a post it goes into the blog’s ‘loop’ (such as in the ‘recent posts’ section), whereas a page is static and stays on the site somewhere in the sidebar (such as an ‘About Us’ or ‘Contact Us’ page).
You may have discovered that some themes will not show the sidebar on WordPress pages. This occurs when you have chosen the ‘static page’ option under the ‘Reading’ menu of the WordPress Dashboard. To fix this, you simply need to read the sidebar to WordPress static pages.
<?php get_header(); ?>
This tells the page to get the themes header, so we will tell the page to get the sidebar.
<?php get_sidebar(); ?>
Make sure you paste this code between the < > brackets and click “Update File”.
