I'm trying to add custom template to my Wordpress theme, which would be static "About" page template. I create about.php file in my twentytwelve folder and put inside content like:
<?php get_header(); ?>
blah blah page content
<?php get_footer(); ?>
When I open this file in browser, I get error "Fatal error: Call to undefined function get_header() in *site_folder_name*\wp-content\themes\twentytwelve\about.php on line 2".
How can I fix this issue?
