 * After upgrading to wordpress 7.0, I had a problem editing posts. When you click
   on the “edit” post, the download starts and is interrupted by a timeout.
 * Together with the support of the FlyingPress plugin, we found out that the problem
   is with your plugin. Below will be information from Flyingpress support:
 * _**Problem: **_**It is a plugin conflict between Real Category Library and WordPress
   7.0.**
 * WordPress 7.0 introduced a new hook called `register_taxonomy_args` that allows
   plugins to modify how taxonomies behave. The **Real Category Library** plugin
   uses this hook to make all taxonomies “hierarchical” (tree-style) so it can display
   them as folder trees in the admin.
 * However, WordPress also uses an internal taxonomy called `wp_theme` to link global
   style settings to the active theme. Real Category Library was also making `wp_theme`
   hierarchical, which broke how WordPress stores that link.
 * Because of this broken link, every time you opened the post/page editor, WordPress
   could not find the existing global styles for your theme. As a result, it created
   a **new one from scratch**.
 * This did not happen on previous WP versions because that did not include the `
   register_taxonomy_args` hook. Therefore, **Real Category Library** had no way
   to interfere.
 * —
 * **Fix**
 * Real Category Library provides its own filter, `RCL/Taxonomy/MakeHierarchical`,
   to exclude specific taxonomies from being made hierarchical.
 * > Please add the following snippet to your child theme’s `functions.php` or via
   > a code snippets plugin:
 * add_filter(‘RCL/Taxonomy/MakeHierarchical’, function($skip, $args, $taxonomy){
   if (in_array($taxonomy, [‘wp_theme’, ‘wp_template_part_area’], true)) { return
   true; } return $skip; }, 10, 3); This code stops the conflict without modifying
   either plugin.
 * **NOTE: After applying this code, 1st time it will be slow, but then it will 
   be normal.**

 * Hi [@procarmanuals](https://wordpress.org/support/users/procarmanuals/) !
 * Thanks for your message. Here is Matthew 🙂
 * Attached, you will find a pre-release of the plugin. This solves the problem 
   you mentioned. You can simply upload this version to your WordPress and replace
   it with the current version (Plugins > Add new > Upload Plugin; [Screenshot](https://i.imgur.com/MsiaDId.png)).
   When the next version of the plugin incl. the pre-released feature is available
   for all users, you will see it as a normal update in your WordPress.
