[Resolved] Custom post type server 404 on translation

Thanks for looking Drazen, but it's the Spanish translation that doesn't work. Spanish is in fact the only translation written for this post. Though the url "works", French is falling back to the English cause it has not been translated to French yet.

Here's the Spanish link, you can see that it goes to a 404.

Or when you land on the English link and then hit the translate button it also going to a 404.

The other one is in English and Portugese

These are the only 2 posts of this post type, media-section, that have translations written and neither work.

Thanks for your continued support!

This was very helpful Waqas! Thank you!

I narrowed the issue down to a pre_get_posts function we added to be able to order these custom posts by an ACF date custom field.

When removed the media-section posts load in their respective translations. When there the media-section posts go to a 404.

Do you have any tips on how I might modify this pre_get_posts function to make it compatible with WPML?

Thank you!

This is what the function looks like.

function my_pre_get_posts( $query ) {
// do not modify queries in the admin
if( is_admin() ) {
return $query;
}

// only modify queries for 'event' post type
if( isset($query->query_vars['post_type']) && $query->query_vars['post_type'] == 'media-section' || isset($query->query_vars['media-type'])) {

$query->set('orderby', 'meta_value');
$query->set('meta_key', 'publication_date_2');
$query->set('order', 'DESC');
$query->set('posts_per_page', 9);

}

// return
return $query;

}

add_action('pre_get_posts', 'my_pre_get_posts');
