Well I figured it out but I had to add remove_all_filters('posts_orderby');
before the $args and had to change order
to DESC
because remove filters reversed the order. Something odd is happening but if someone has an explaination as to why this works please let me know.
remove_all_filters('posts_orderby');
$args = array (
'post_type' => 'exhibitions',
'meta_query'=> array(
'relation' => 'AND',
array(
'key' => 'exhibition_status',
'value' => 'current',
),
array(
'key' => 'end_date',
'compare' => 'EXISTS',
),
),
'meta_key' => 'end_date',
'orderby' => 'meta_value',
'order' => 'DESC',
'post_status' => 'publish',
'posts_per_page' => 10,
'paged' => get_query_var( 'paged' ),
);
