This aims to make the update process more reliable and ensures that if a plugin or theme update fails, the previous version can be safely restored. * When updating a plugin or theme, the old version is moved to a temporary backup directory: * `wp-content/upgrade-temp-backup/plugins/[plugin-slug]` for plugins * `wp-content/upgrade-temp-backup/themes/[theme-slug]` for themes. * If the update fails, then the backup kept in the temporary backup directory is restored to its original location. * If the update succeeds, the temporary backup is deleted. To further help troubleshoot plugin and theme updates, two new checks were added to the Site Health screen: * A check to make sure that the `upgrade-temp-backup` directory is writable. * A check that there is enough disk space available to safely perform updates. To avoid confusion: The temporary backup directory will NOT be used to “roll back” a plugin to a previous version after a completed update. This directory will simply contain a transient backup of the previous version of a plugin or theme being updated, and as soon as the update process finishes, the directory will be empty. Follow-up to [55204], [55220].
