Disable sidebar in a particular page

Is it possible somehow to disable sidebars on a particular page

yes. you have to find the template page from which you are calling simple:press – most likely page.php, unless you have created a custom page template.

within that file, find the line that calls the sidebar, it will possibly be like this: <?php get_sidebar(); ?>

wrap it in an if statement

<?php if(!is_page('forum')) {
         get_sidebar();
      }
?>

instead of the word forum in my example, use the page slug (URL) of the page from which you are calling simple:press

this code will load the sidebar on all pages except the forum page

Thanks for this post. It worked for me. I was able remove the side bar on my about page. I want to also remove the side bar on my links page. How do I put more than one page in this if statement?

<?php if( !is_page('About') && !is_page('Links') ) {
         get_sidebar();
      }
?>
