If you’re managing a WordPress website along with several other people and you need some way of tracking what was changed (e.g. a menu tweak or an edit somewhere), when and by who there’s a plugin for that.
Called Simple History, simply install and active this plugin and it’ll automatically track all changes that are made in the WordPress admin itself.
To view the changes go to Dashboard > Simple History from the WordPress menu.
From there you can search by keyword or browse through a certain time period.
It could even be useful if you’re the only one working on a WordPress website but you’d like a simple record of what you’ve changed.
(Bear in mind it won’t retrospectively show any changes that have been made in the WordPress admin before you installed and activated the plugin. Only changes that have been made after the plugin is activated).
