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/markrusselldev/wp-mu-plugins/archive/refs/heads/main.zipA 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is ever lost the post can sit unpublished indefinitely.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.
