 * Hello!
 * I am having an issue getting my categories to be effectively hidden from the 
   home page…
 * I’m not sure why the code isn’t working, but I think I might possibly have some
   coding conflict.
 * in my Theme Functions, I have the following:
 *     ```
       function limit_posts_per_page() {
       	if ( is_home() )
       		return 9;
       	else
       		return 99; // default: 99 posts per page
       }
       ```
   
 * And also:
 *     ```
       add_filter('pre_option_posts_per_page', 'limit_posts_per_page');
       function limit_posts_per_archive_page() {
       	if ( is_category() )
       		set_query_var('posts_per_archive_page', 99); // or use variable key: posts_per_page
       }
       add_filter('pre_get_posts', 'limit_posts_per_archive_page');
   
       function my_home_query( $query ) {
         // not an admin page and is the main query
         if (!is_admin() && $query->is_main_query()){
           if(is_home()){
            //cat=-94, -158"."&posts_per_page=9
             $query->set('cat', -94, -158);
             $query->set('posts_per_page', 9);
           }
         }
       }
       add_action( 'pre_get_posts', 'my_home_query'
       );
       ```
   
 * If anyone could help me with this, it would be greatly appreciated!
 * Thank you in advance!

 * P.S. I am trying to utilize this on post that belong to more than one category,
   I might add. I understand there are some issues associated with this?
