wp-mu-plugins

A small collection of single-purpose WordPress must-use plugins - each one file, no settings, no dependencies.

Must-use plugins load automatically from wp-content/mu-plugins/, before regular plugins, with no activation step and no way to deactivate them from the admin. That makes them a good fit for small, always-on fixes you want to be sure are running.

Install

Copy the file you want into your site's wp-content/mu-plugins/ directory (create the folder if it does not exist). That's it - it is active immediately. To remove one, delete the file. None of these store options or database tables, so removal is clean.

Plugins

missed-schedule-rescue.php

Publishes any post stuck in future past its scheduled time. WordPress publishes a scheduled post through a single one-shot publish_future_post event and has no fallback, so if that event is ever lost the post can sit unpublished indefinitely. This runs a small sweep on every cron run and publishes anything overdue. It hooks wp_loaded and gates on wp_doing_cron(), so it rides the physical cron trigger and does not depend on any stored event surviving. Requires a working cron (WP-Cron or a real server cron hitting wp-cron.php).

no-user-enumeration.php

Blocks the two common public user-enumeration vectors so login usernames stay private: numeric ?author=N scans (which core would redirect to /author/<slug>/) and the anonymous REST /wp/v2/users endpoint. Logged-in requests - the editor and other authenticated tools - are left untouched.
