This test warns when the site runs an outdated PHP version. Older PHP releases stop receiving security fixes and can break newer WordPress features and plugins.
Check the current version in your host panel, or from Security Ninja debug / server info tools if available. Upgrade through your host control panel or ask support to move you to a supported PHP release.
Before you switch:
- Confirm your theme and plugins support the target PHP version.
- Test on staging when possible.
- Keep a recent backup.
Updating PHP pairs with keeping WordPress, themes, and plugins current.
