Hi,
- To add a sidebar to your posts, add the code below in your child theme’s functions.php file.
function add_posts_sidebar($layout) {
if(is_singular('post')){
$layout= 'content-sidebar';
}
return $layout;
}
add_filter('x_option_x_layout_content', 'add_posts_sidebar',999);
- To remove those information below your post title, turn off post meta under Appearance > Customize > Blog > Content > Post Meta.
- The author at the end of the article is being added by third party Starbox plugin. I am not exactly sure how that plugin works but you can check it’s settings and see if you can disable it.
Thanks
