Question

I have a taxonomy with posts assigned to terms, and on the term archive page i get no found post

$rewrite = array(
    'slug'                       => 'mytax',
    'with_front'                 => true,
    'hierarchical'               => false,
);
$args = array(
    'labels'                     => $labels,
    'hierarchical'               => true,
    'public'                     => true,
    'show_ui'                    => true,

EDIT 2

i try to add a new taxonomy , add a term to this taxonomy and add a post with this taxonomy, but the taxonomy leave after update the post

Answer 1

your code seems to be correct.

Here is the process to debug it:

• As your code is correct (what I can see), you need to update your htaccess. To perform it, go to the permalinks WP section and save again permalinks (keep your structure).
• If not working, you need to flush rewrite rules on your function.php template
• If not working, you need to check the name of your custom template
• If not working, you need to remove your query variable with static variables (to find the if this is a template issue - wp template condition as been tested before)
• If not working, from an empty project, add you CPT an CT to review if there is any problem with plug-in etc
• If not working, send me a link to your staging server, I will find the issue in less than 5 min.

Hope this help
