Disable Categories for Posts
Removes categories from posts: the Categories menu, the editor panel and the column in the posts list.
Snippet Library
Disable Features snippets for WordPress
Snippets that switch off WordPress features you do not use: comments, the block editor, RSS feeds, automatic updates, attachment pages and more. One snippet per feature, so you turn off exactly what you want and nothing else.
Disable Comments Completely
Turns comments off everywhere: closes comments and pings, hides existing comments, and removes the Comments menu, admin bar item and comment feed links.
Disable Tags for Posts
Removes the Tags taxonomy from posts: the Tags menu, the tag box in the editor and the tag column disappear.
Disable the Image Lightbox Option
Removes the "Expand on click" lightbox setting from Image blocks and turns the lightbox off.
Remove "Private:" and "Protected:" From Titles
Shows private and password-protected posts with their plain title, without the prefix WordPress adds.
Stop Changing "Wordpress" to "WordPress"
Disables the filter that silently rewrites the spelling of WordPress in titles, content and comments, which can break URLs or quoted text.
Stop Converting Text Smileys to Images
Leaves text like :) and ;-) as typed instead of replacing it with smiley images or emoji.
Stop WordPress Guessing URLs on 404 Pages
Turns off the automatic redirect WordPress makes when a URL does not exist but looks similar to a post slug, so wrong URLs show a real 404.
Turn Off the Visual Tab in the Classic Editor
Makes the classic editor open in Text (HTML) mode only, for sites where the visual editor keeps changing hand-written markup.
