Install
This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.
Install straight from GitHub with WP-CLI:
wp plugin install https://github.com/robertandrews/cwp-disable-taxonomy-categories/archive/refs/heads/master.zipNo built-in updater. New versions won't appear under Dashboard → Updates. Install new releases yourself, or let Git Updater track the repository.
Context WP Taxonomy Disable Categories
Description
Disable the default "Categories" taxonomy in WordPress.
WordPress ships with two default taxonomies - Categories and Tags.
Admins who wish to use specific custom taxonomies may wish to disable these, to force users to use appropriate taxonomies only.
This plugin runs register_taxonomy('category', array()); during the init action.
