Page uses outdated web features that may stop working

What this means for your business

Your site uses web features that major browsers are phasing out. These may stop working in upcoming browser updates, potentially breaking parts of your site for visitors without warning.

How to fix it
Hard
1–4 hours

  1. 1Deprecation warnings mean your site is using old browser features that will stop working in future browser updates. It's not broken today, but it will be.
  2. 2The most common cause is outdated plugins or apps. Update everything to their latest versions first — most deprecation warnings are already fixed in newer releases.
  3. 3If updates don't clear the warnings, identify which plugin or tool is the source and contact the developer or look for a modern alternative.
  4. 4If you built the site yourself or have a developer: ask them to open the browser console (right-click → Inspect → Console tab) and look for yellow deprecation warnings. The warning will name the specific feature and often link to the modern replacement.
  5. 5Set a reminder to revisit this if it can't be fixed immediately — browsers eventually remove deprecated features, at which point the affected functionality will break completely.

On WordPress

Go to Dashboard → Updates — you'll see all plugins, themes, and WordPress core with available updates in one place. Check the changelog for any flagged plugin (click "View version details") to confirm the deprecation is fixed before updating.

On Shopify

Shopify's platform is kept current automatically, so warnings here come from theme code or apps. Open the Shopify App Store, find the app in question, and check its "Last updated" date — if it hasn't been updated in over a year, look for a modern replacement.
