[Support request] I would like to get 12 post on the homepage and 16 on the other pages

Hi there,

Can you link us to the homepage and the other pages you are referring to?

1. Go to settings > reading, and set the Blog pages show at most to 16.

2. Add this PHP snippet:

add_action( 'pre_get_posts', 'yh_query_offset', 1 );
function yh_query_offset( &$query ) {
        if ( is_admin() ) {
            return;
        }

	// Before anything else, make sure this is the right query...
	if ( ! ( is_main_query() ) ) {
		return;
	}

        // Don't do anything to Elements.
        if ( 'gp_elements' === $query->get( 'post_type' ) ) {
            return;
        }

	// First, define your desired offset...
	$offset = -4;

	// Next, determine how many posts per page you want (we'll use WordPress's settings)
	$ppp = get_option( 'posts_per_page' );

	// Next, detect and handle pagination...
	if ( $query->is_paged ) {

		// Manually determine page query offset (offset + current page (minus one) x posts per page)
		$page_offset = $offset + ( ( $query->query_vars['paged']-1 ) * $ppp );

		// Apply adjust page offset
		$query->set( 'offset', $page_offset );

	}
	else {

		// This is the first page. Set a different number for posts per page
		$query->set( 'posts_per_page', $offset + $ppp );

	}
}

add_filter( 'found_posts', 'yh_adjust_offset_pagination', 1, 2 );
function yh_adjust_offset_pagination( $found_posts, $query ) {
        if ( is_admin() ) {
            return;
        }

	// Define our offset again...
	$offset = -4;
	//get posts per page from WP settings
	$ppp = get_option( 'posts_per_page' );
	$real_page_numbers =ceil(($found_posts - $ppp - $offset) / $ppp) + 1;

	// Ensure we're modifying the right query object...
	if ( is_main_query() && ! is_paged() ) {
		// Reduce WordPress's found_posts count by the offset...
		return $real_page_numbers * ($ppp + $offset);
	}
	 return $real_page_numbers * $ppp;
	
}

Adding PHP: https://docs.generatepress.com/article/adding-php/

The query in the sidebar is the same as the main query of the blog, these are repeated content which I don’t think is good for SEO.

Will you consider removing them from the blog?

In that case, I would recommend reaching out to the plugin support and asking how to target their loop.

Show them the PHP snippet, they should be able to help!

No Problem, glad to help 🙂
