WordPress updates are essential — 56% of hacked WordPress sites had outdated plugins or core. But updates applied carelessly are also one of the most common causes of broken sites. Follow this checklist and you'll never be stuck choosing between security and stability again.
⚠️ Never run major WordPress core updates or multiple plugin updates at once on a live site without a backup. One incompatible plugin can bring the whole site down.
Before any update, run a full backup — database and all files. If you have UpdraftPlus or Jetpack Backup, trigger a manual backup now. If you're on managed WordPress hosting, use their snapshot feature. There is no safe update without a current backup to roll back to. See our guide on WordPress backup frequency and strategy.
Before updating, click the "View version X.X details" link on each update. Look at the changelog — does it mention "breaking changes"? Does it require a newer PHP or WordPress version? A 60-second review can save hours of troubleshooting.
A staging environment is a copy of your site where you can test changes safely before applying to live. Many managed hosts (WP Engine, Kinsta, SiteGround) offer one-click staging. If you don't have one, consider creating a subdomain staging site using WP Staging plugin.
Don't click "Update All." Update each plugin individually, then do a quick visual check of your site — homepage, key pages, admin — before moving to the next. This way, if something breaks, you know exactly which plugin caused it.
Update your active theme. If you've made changes directly to theme files, you'll lose them — always use a child theme for customisations. Check your site's visual design carefully after theme updates, especially header, footer, and homepage layout.
After plugins and themes are confirmed working, update WordPress core. Minor releases (6.5.1 → 6.5.2) are almost always safe. Major releases (6.5 → 6.6) occasionally cause plugin conflicts — test on staging first if you have one.
Check: homepage loading correctly, all menu items working, contact form submitting, WooCommerce checkout completing (if applicable), admin dashboard functioning normally, and mobile layout intact. Use a different browser or private/incognito mode to ensure you're seeing the live site, not a cached version.
✅ Once all updates are complete and tested, purge your site's cache (in your caching plugin settings) to ensure visitors see the updated version immediately.
WordPress 5.5+ allows automatic plugin and theme updates. For security, enabling automatic minor core updates is highly recommended — these are vetted security patches. For plugins, automatic updates are good for actively maintained plugins from reputable developers. For major core releases, test manually first.
How often should I update WordPress plugins?
At least weekly. Set a recurring calendar reminder to check for and apply updates every Monday or Friday. Leaving updates more than 2–3 weeks behind significantly increases your vulnerability window.
Is it safe to update WordPress core right away when a new version releases?
For minor security releases, yes — apply immediately. For major feature releases, waiting 1–2 weeks lets the community surface any major compatibility issues with popular plugins before you apply it to your live site.
Can I undo a WordPress update?
Not directly through the dashboard. You can restore a backup (easiest), or manually revert by uploading older plugin/theme files via FTP. This is why the backup step is non-negotiable.
