How to not show a specific Category in the Blog Layout on the Home page?

Hi there,

this is the PHP Snippet you require:

function exclude_posts_from_home_page( $query ) {
    if ( $query->is_home() && $query->is_main_query() ) {
        $term_id = get_cat_ID( 'term-slug' );
        $query->set( 'category__not_in', array( $term_id ) );
    }
}
add_action( 'pre_get_posts', 'exclude_posts_from_home_page' );

In the code you will see: $term_id = get_cat_ID( 'term-slug' ); change the term-slug to match your term.

Question - are you using a Child Theme?
If Yes, then add the code to your Child Themes functions.php

If NO, then install the Code Snippets plugin, Add New Snippet and add the code there.
