How to exclude or remove the posts of one category from WordPress blog feed on front home page

If you are using WordPress for your website you may want to exclude or remove the posts from one category of your blog from the blog feed on your website on the front page there. You can then add this code to your functions.php file. You may want to backup your WordPress website before you make updates to it on there.

/**
 * remove category from blog feed on front page
 *
 * @author WPSnacks.com
 * @link https://www.wpsnacks.com
 */
function remove_category_from_blog( $query ) {
    if( $query->is_main_query() && $query->is_home() ) {
        $query->set( 'cat', '-#' );
    }
}
add_action( 'pre_get_posts', 'remove_category_from_blog' );

You can then replace the # with the id number of the category you want to remove from it. This post may help you to find the category id number on there. Now if that works for you it would remove that category from the blog feed on the front page of your WordPress website on there.
