Custom taxonomies that were developed prior to the release of WordPress 5.0 (the Gutenberg release) may not be compatible with the WordPress block editor.
Custom taxonomies require that the “show_in_rest” property be set to “true” in order to work with the block editor. “show_in_rest” was added with WordPress 4.7 and the integration of the WordPress JSON REST API. Sites using custom taxonomies that were created prior to this likely do not have this property set. Additionally, the default value for “show_in_rest” is “false” (this is poorly documented), ergo older custom taxonomies will not appear in the WordPress block editor interface.
This plugin will take any custom taxonomy where the “show_in_rest” feature is set to “false” and change it to “true”. It will not add any additional REST properties, such as “rest_base” or “rest_controller_class”. If you need those properties set for any reason, you will need to update your custom taxonomy where it is being registered.

Custom Taxonomies for Blocks

WordPress plugin to convert older custom taxonomies so they can be used in the WordPress blocks interface (a.k.a. Gutenberg).

In addition to controlling your custom post type permalinks this plugin adds support for using custom taxonomies in your permalink structures as well.
Not only that but you can control the full permalink so the post type slug is not required at the start of the link.
Multiple post types can use the same permalink structure.
<h4>Usage</h4>
There are 2 ways to use this plugin:
Permalink Settings
The plugin adds fields to the permalinks settings page for any public facing custom post types.
In Code
When registering a post type you can add a value to the rewrite property with the key ‘permastruct’ to define your default permalink structure.
eg:
<pre><code><?php

register_post_type( 'my_type', array(
 ...
 'rewrite' => array(
 'permastruct' => '/%custom_taxonomy_name%/%author%/%postname%/'
 ),
 ...
) );

?>
</code></pre>

WP Permastructure

Adds the ability to configure permalinks for custom post types using rewrite tags like %post_id% and %author%.
