What to Check Before Updating Your WordPress Website

The 10-Point Pre-Update Checklist

1. Back up everything (files + database) and test a restore.
2. Check PHP and WordPress version compatibility for your theme and plugins.
3. Review changelogs for high-risk changes (database, major refactors, deprecated functions).
4. Update on a staging site first; only then deploy to live.
5. Disable full-page caching layers before updating (plugins, server cache, CDN).
6. Put the site in maintenance mode (or a low-traffic window) and notify editors.
7. Verify disk space and database health (optimize tables, fix overhead).
8. Confirm you have admin/SFTP/hosting access and a one-click rollback plan.
9. Take “before” screenshots of critical pages and funnels.
10. After updating, purge caches and run a post-update test pass (forms, checkout, speed).

1) Make a Complete Backup – and Test It

“Complete” means both files (themes, plugins, uploads) and the database. If you can’t confidently restore your site from backup, you don’t have a real safety net. Take five minutes to verify that your backup file can actually be restored on a staging or local environment.

• Files: wp-content (themes, plugins, uploads) + wp-config.php.
• Database: Export via your backup plugin or your hosting panel.
• Test: Restore on staging to confirm the backup isn’t corrupted.

2) Check Compatibility (PHP, WordPress, Theme & Plugins)

Conflicts usually happen when one component expects a newer (or older) version of PHP or WordPress core. Check the requirements for your theme and mission-critical plugins.

• WordPress core → Theme: If you’re using Enfold with a child theme, ensure your child overrides don’t rely on deprecated hooks or functions.
• Plugins: Confirm they’re tested up to your target WP version. Pay special attention to form builders, SEO, caching, and e-commerce plugins.
• PHP version: Many plugins now require PHP 8.x. If your host runs an older version, consider upgrading PHP before updating WordPress.

Pro tip: Scan plugin/theme changelogs for database migrations or breaking changes.

3) Read Changelogs for Red Flags

Changelogs reveal whether an update is routine or risky. Look for keywords like “database schema change,” “deprecated,” “major refactor,” “breaking change,” or “requires re-index.” For big jumps, plan extra time on staging for testing.

4) Use a Staging Site First

A staging site is a clone of your live website where you can safely update and test without affecting visitors or SEO. Update everything on staging, test, and only then push to live.

• Content freeze: Ask editors to pause new posts while you sync staging back to live to avoid overwriting changes.
• Search visibility: Keep staging noindex (Search Engine Visibility off) so Google doesn’t index it.
• Sensitive keys: Disable third-party integrations (e.g., live payment gateways) on staging if possible.

5) Turn Off Caching Layers During the Update

Caching can mask problems and sometimes block a clean update. Temporarily disable:

• Cache plugins: Purge and disable page/object cache.
• Server cache: Turn off reverse proxy or dynamic cache if your host uses one.
• CDN: Bypass the CDN or put it in development mode. Purge after the update.

6) Maintenance Window & Communication

Choose a low-traffic window (e.g., late night) and let your team know. If you expect a few minutes of downtime, enable a friendly maintenance page with your logo and a contact link. This protects user experience and avoids half-edited posts being saved during updates.

7) Database Health & Disk Space

Updates often write new data. If your storage is full, an update can fail mid-way. Check:

• Disk space: Ensure sufficient free space (backups + updates + logs).
• DB overhead: Optimize tables and run a quick integrity check.
• Error logs: Clear old logs; review for warnings that hint at conflicts.

8) Confirm Access & Rollback Options

Have admin access, SFTP/SSH, and hosting panel access ready. Know how to roll back quickly:

• Restore the last known-good backup.
• Manually replace a broken plugin via SFTP (rename the folder to deactivate).
• Switch to a default theme to isolate theme-related issues.

9) Snapshot Key Pages & Funnels

Take “before” screenshots so you can visually confirm nothing broke. Include:

• Homepage hero and main CTA
• Service pages (e.g., “WordPress Website Development Bangkok”)
• Contact/lead forms and confirmation screens
• E-commerce: product page, cart, checkout, thank-you

10) Post-Update Test Pass

After the update (on staging and then again on live), run through a quick QA:

• Forms: Submit a test; confirm notifications arrive.
• Speed: Check for obvious slowdowns; then re-enable and warm caches.
• Layout: Scan for broken grids, icons, fonts (common after CSS/JS changes).
• Console: Look for JavaScript errors (often a plugin conflict).
• Security: Re-enable firewall/rate-limit and verify no new alerts.

FAQ: Updating WordPress Safely

Do I really need a staging site?

Yes for most business sites. Staging lets you catch conflicts without risking revenue or SEO on the live site.

How often should I update?

Minor security updates: ASAP. Regular plugin/theme updates: weekly or monthly. Major core updates: test first on staging.

What if I use Enfold with a child theme?

Keep Enfold up to date, but review your child theme customizations for deprecated functions. Test on staging and check your custom templates after updating.

Can I skip an update?

Don’t skip security updates. If a feature update is risky, wait for a point release while monitoring the changelog and support forums.

What if the site breaks after an update?

Roll back immediately (restore backup), then isolate the conflict by disabling the last updated plugin/theme, checking the error logs, and re-testing on staging.
