# Time Machine

The **Time Machine** allows you to roll back to previous versions of WordPress core, plugins, and themes.

This is particularly useful if an update causes a conflict or makes your site inaccessible.
Instead of spending hours troubleshooting, you can simply undo the update by reverting to the stable, previous version.

#### How to use the Time Machine:

1. Select the specific version (WordPress, plugin, or theme) you wish to reinstall.
2. Click the **"Roll Back"** button.
3. A pop-up will appear asking you to confirm the action.

**⚠️ Important Warnings:**
* **Compatibility:** While almost nothing is irreversible at Copilhost, choosing a version that is too old can cause issues. For instance, an outdated theme might conflict with recent plugin versions, potentially leading to display or functional errors.
* **Going back to the latest version:** If you want to return to the current version, simply go back to the **"Plugins & Themes"** tab and run the update as usual.
