A site rollback returns WordPress files and the database to an earlier working state. When the database has already changed, the old files no longer fit the new data structure and the site can keep failing. WordPress stores content, settings, and structure in the database. An update can rewrite that structure in a way file replacement alone cannot undo.

Why does the site ask for a database update?
Core updates often arrive in two stages: new files first, then a database change. When the files are newer than the version recorded in the database, WordPress shows the database update required screen.
Hostaccent notes in its database-update explanation the standard fix is to back up, then open wp-admin/upgrade.php and choose Update WordPress Database. Developer.WordPress.org documents wp core update-db, with –network to update all sites and –dry-run to compare versions without updating.
Why will older files not undo the change?
A plugin update can add tables, fields, or settings to the database. WPOneCare reports in its plugin-breakage guide that reinstalling only older files leaves those newer changes behind and errors can continue.
The same gap affects themes. ErgoSEO explains that rolling back only theme files leaves settings, layouts, and generated data in the database unchanged, so prior behavior does not return.
Why is restoring only half the site risky?
Files and the database work as a pair. Pagely warns that restoring only files or only the database can make a broken site worse and advises expert handling for core rollbacks.
Developer.WordPress.org warns in its upgrade guide that without a full site and database backup made before upgrading, a successful rollback is near impossible. Recovery then requires re-uploading backed-up files plus restoring the database backup.
What do you lose with a full restore?
A full database restore moves the whole site back to the backup moment. Protuno notes that every order, form entry, and comment created since then is destroyed.
That loss hits active sites hardest. WooCommerce stores, membership sites, and forums can suffer more harm from missing transactions than from the original failure.
How can stores save recent orders?
Shop owners face a hard trade between fixing the fault and keeping new sales. WordPress.com Support describes a way to exclude WooCommerce tables such as wp_wc_orders to preserve data created after the backup date.
The method keeps new orders while bringing back earlier files and other tables. If data still goes missing, the documented fallback is to restore a more recent backup.
- Confirm the backup date and list transactions made since then.
- Ask the host whether order tables can be left out of the restore.
- Fall back to a newer backup if orders disappear after restore.
