Identify what changed
Before rolling back, record the plugin and WordPress versions, PHP version, update time and observed failure. Check the plugin's release notes for database migrations and supported downgrade procedures. Copying older plugin files back does not necessarily reverse a database change made by the newer version.
Take a current backup of files and database, and confirm where a known-good backup can be restored. For a live store or membership site, a full database restore can discard orders, registrations and content created since the backup. Agree how those changes would be preserved or reconciled.
Rehearse on staging
Restore a representative copy to an isolated environment. Disable or redirect real email, payment and webhook integrations. Reproduce the issue and follow the vendor's supported rollback procedure. Check logs and test the data that the plugin owns, not just the WordPress dashboard.
If the old code is incompatible with the updated database, evaluate a vendor-supported forward fix or a coordinated recovery. Avoid manually changing database schema or serialized settings without a documented procedure.
Return to service
Apply the selected change in an agreed window, retaining the current backup and a way back. Test login, the affected plugin workflow, scheduled jobs and a representative customer journey. For commerce, reconcile recent transactions with the payment provider rather than creating uncontrolled test charges.
Record the cause, versions and follow-up. Keep security implications of an older plugin in view and plan a tested update; rollback is an incident response, not a permanent security strategy.
