I have really been struggling with getting the main loop for the index.php to work properly with WP_Query functions. I need the grid array of 6 featured images at the top to not be offset at all, while offsetting the main posts loop below it by 6 posts.
Anything involving query_posts() inevitably ends up breaking the pagination. Using a single loop fixes the pagination issue, but undesirably applies the offset to the featured grid section. I have managed to get the pagination main loop to work using WordPress codex's recommended fix of pre_get_posts https://codex.wordpress.org/Making_Custom_Queries_using_Offset_and_Pagination. However, this fix overwrites the featured posts loop settings by 6 as well.
The offset/pagination dilemma seems to be a well known issue to WordPress developers, and I've browsed dozens of articles, forums, and tutorials but I can't find much documentation on what to do when the pre_get_posts fix overrides other custom loop settings on the index. The pre_get_posts works to a degree, I just want the formatting to only apply to the main posts loop on the home page, not the top 6 posts.
Here is the code. Thanks for taking the time to read this.
index.php:
<?php get_header();
do_shortcode( '[mg-masonry_js]' );
$options = get_option('mg_options');
$option_cats = $options['mg-posts-categories'];
$option_pg_number = $options['mg-posts-post-per-page'];
$args = array(
'post_type' => 'post',
'post_status' => array( 'publish' ),
'posts_per_page' => $option_pg_number,
'orderby' => 'date',
'order' => 'DESC',
'cat' => $option_cats,
'offset' => 0,
);
?>
