CTP-onomies broke child-parent relation

Hmm. I’ve never heard of this issue. Any chance you can get your hands on the query info? That might help us. And/or your CPT-onomy settings. What’s the URL for your taxonomy archive?

The following will print the query out on the page for you. Warning: the following will print the query out on the page for you.

add_action( 'pre_get_posts', 'my_website_print_wp_query' );
function my_website_print_wp_query( $query ) {
   echo "<pre>";
   print_r( $query );
   echo "</pre>";
}

URL: https://site.name/recepty/vtorie-blyuda/
/recepty/ <- main archive for “recept” CTP
/vtorie-blyuda/ <- parent category

When CPT-onomies disabled:

[ 913 lines of code moderated, that’s just way too much. For that many lines of code please use pastebin.com instead. ]

I hope this will be useful for you. Tell me if you need more information.
Thank you again for help!

Do you still need help? If so, the code you sent didn’t show up. Says you need to use pastebin.com.

It’s boring that my code has been removed ??

Yes, the problem persists.

In all cases, loading taxonomy-recipe_type.php that you can find in my previous post.

Thank you for your help again!

I’d recommend looking in the Help section of the CPT-onomies settings page, visiting the “Troubleshooting” tab and checking out the “When I try to retrieve CPT-onomy AND taxonomy terms, the results are incorrect” section. I wonder if this is your problem.
