What happens if you add $query->is_main_query() to your if statement?
function allstar_buzzworthy_published_sort( $query ) {
// If not the admin section
if ( !is_admin() && $query->is_main_query()) {
// If on a taxonomy page
if ( is_tax() ) {
$query->set( 'meta_key', 'date_published' );
$query->set( 'orderby', 'meta_value' );
$query->set( 'order', 'DESC' );
}
}
}
add_action( 'pre_get_posts', 'allstar_buzzworthy_published_sort' );
The issue for me was specific to $query->set('s', ' ');. I added it to fix empty search queries returning a 404 page.
I set a bunch of other query vars in the same function but going through one by one, this was the only one to cause error.
Btw, you’re missing a single quote before date_published.
function property_filters($query) {
// ...
/**
* Fixes issue with blank search queries returning 404
*/
if (!is_admin() && isset($query->query_vars['s']) && empty($query->query_vars['s'])) {
$query->set('s', ' ');
}
}
add_action('pre_get_posts', 'property_filters');
I am also seeing the same behaviour after upgrading to Gallery 1.1.0 and ACF 4.3.0.
With add_action('pre_get_posts'... called in functions.php, get_field for a gallery field returns an empty array.
If I comment out the pre_get_posts action everything works as expected.
