Answer 1

Thanks guys, it worked thanks to @rnevius

The problem was in my query, I was using WP_Query() and query_posts().

I used how reference the WP Codex: https://codex.wordpress.org/Class_Reference/WP_Query

Below is how my code was at the end:

 'post',
    'post_status' => 'publish',
    'category__not_in' => array( 44 ),
    'posts_per_page' => 9,
    'paged' => get_query_var('paged')
  );
  $query = new WP_Query( $args );
?>

have_posts() ) {
    while ( $query->have_posts() ) {
      $query->the_post();
?>
