[Plugin: Hierarchy] Undefined Index

  • When installing Hierarchy on my local machine with WP_DEBUG set to true I get the following error:

    Notice: Undefined index: post in /Users/tim/Documents/HTDOCS/wp-content/plugins/hierarchy/hierarchy.php on line 425

    I’m not PHP expert, but it seems to be something wrong with the way you are detecting WordPress 3.4 and adjusting the data structure here:

    $struct = $wp_rewrite->extra_permastructs[$post_type]['struct'];
