The sidebar is a very important element of your blog, but sometimes, you just don’t want it to be displayed on your homepage. If you’d like to know how to do, just read this recipe.
To hide your sidebar on your blog homepage, edit the index.php file from your theme and look the the following:
<?php get_sidebar(); ?>
Replace it by the code above:
<?php if (!is_front_page()) { get_sidebar(); } ?>
That’s all. Your sidebar will now be displayed on all pages, exept your blog homepage.
