Activity Log with Undo

An activity log where every change you can reverse has an Undo button.

Follow it on GitHub

Use it when

  • you need to know who changed what, and put it back.

What it does

Activity logs tell you what changed. They do not help you put it back. Someone changed the site title, deactivated the wrong plugin, gave a user the wrong role or deleted a category, and now you have to remember what it was before.

Activity Log with Undo logs each change together with what it was before, and gives every change it can reverse an Undo button.

What it logs, and what Undo does:

  • Settings and widgets: the settings people change on purpose. That is everything on the core Settings screens, permalinks, the privacy page, widgets, Customizer settings, and options plugins register with the Settings API. Undo writes the old value back. Other plugins’ caches, indexes and counters are left out, and so are settings changed by a cron job or a visitor’s page view.
  • Plugins: activation and deactivation, undone by switching back. Installs, updates and deletions are logged only, because WordPress keeps no copy of the old files.
  • Themes: a theme switch, undone by switching back while the old theme is still installed.
  • Users: role changes, display name, email and website, all undoable. Undoing a new user deletes the account and gives their content to whoever added them, after you confirm. Deleted users are logged only.
  • Posts, pages and other content: publish, unpublish, trash and restore, edits to the title, content and excerpt, and changes to the slug, parent, author, featured image and template. Content edits come back through the matching revision when the post has one.
  • Categories, tags and other terms: new, edited and deleted. A deleted term is rebuilt with its meta, posts and child terms. With Category & Tag Trash active, it is restored from that trash instead.
  • Menus: the whole menu with its items is kept before each save, and Undo puts it back.
  • Site Editor: global styles, templates, template parts and navigation. Undo restores the previous revision, removes a new customization, or brings back one you cleared.

Free and open source under the GPL. No pro version, no upsells, no ads in wp-admin, no tracking. And it stays that way.

Safe to undo

  • Changed since? Undo only runs straight away when things still look the way the change left them. If someone changed it again, you see the differences and choose Undo anyway, or leave it.
  • One save, one undo. Changes made in the same request are a change set. Saving Settings > Reading changes several options, and one Undo puts them all back.
  • You see what else goes back. When a change set holds more than one change, the confirm lists the others first. On WP-CLI too, unless you pass --yes.
  • Only your changes. Another plugin’s state that happened to change in the same request is never part of your undo.
  • Undo is logged too, so it can be undone. That is your redo.
  • Before and after, side by side. A word diff for text, a table for everything else.

Find a change

Tools > Activity Log lists every change with who made it and how: the dashboard, the REST API or block editor, an application password, WP-CLI, a scheduled task, XML-RPC or an AI agent through the Abilities API. Filter by event, user, source, dates and object, or search. Select several rows to undo them in one go.

Turn on "Undo last change" in the admin bar to undo your own most recent change from any screen.

From the command line

$ wp activity-log-with-undo list --since="1 day ago" --undoable
$ wp activity-log-with-undo show 42
$ wp activity-log-with-undo undo 42
$ wp activity-log-with-undo undo 42 --force
$ wp activity-log-with-undo purge --older-than=30
$ wp activity-log-with-undo cleanup --dry-run
$ wp activity-log-with-undo settings --retention-days=30 --ip=off

For AI agents

On WordPress 6.9 and later, three abilities let an agent list the activity, read one change with its before and after state, and undo it. Undo refuses when things changed since, unless the agent passes force.

With Agent Governance active, a change an agent made after someone approved its request says which agent it was, the request number, and who approved it.

Privacy

Entries are kept for 90 days by default. IP addresses are shortened by default, and can be kept in full or not at all. The log takes part in the WordPress personal data export and erase tools: erasing keeps the change history and removes the person from it.

Questions

Why can some changes not be undone?

Undo needs the state from before the change. Plugin and theme updates replace files WordPress does not keep, and a permanently deleted post or user is gone with everything attached to it. Those are logged, with the reason shown next to them. A change whose old value is bigger than the size limit (256 KB by default) is logged without it and cannot be undone either.

What happens if someone changed it again after the entry?

Undo stops and shows what is different between the logged change and now. Use Undo anyway to put the old version back and overwrite the later change, or leave it.

Does it log changes made with WP-CLI?

Yes, and the source shows as WP-CLI. Every WP-CLI command is its own change set.

Will it fill up my database?

No. It logs settings, not every option another plugin writes, and each option is logged at most 20 times a minute. A setting value over 64 KB is logged without the value. If the log still grows past 512 MB, new changes are logged without their old values and Site Health tells you. Entries older than 90 days are deleted once a day. Change the period on the Settings tab, turn off the kinds of changes you do not need, or run wp activity-log-with-undo purge. All of these limits have filters.

Why is a change to my plugin’s option not in the log?

The log keeps settings people change on purpose. If your plugin saves its settings with the Settings API (register_setting()), they are logged. For anything else, add the option name to the activity_log_with_undo_logged_options filter.

I updated from an earlier version and the log is huge.

Version 1.0.0 logged every option, so other plugins’ internal state could fill the table. After the update, administrators see a notice that counts those entries and offers to delete them. wp activity-log-with-undo cleanup does the same from the command line.

I use Category & Tag Trash. Who restores deleted terms?

Category & Tag Trash keeps deleted terms with their posts and menu links. When it is active, Undo restores the term from its trash, and the entry links to it.
