This test looks for active plugins that do not declare compatibility with your current WordPress version. Mismatches can cause white screens, broken admin screens, or insecure abandoned code.
Check each plugin’s WordPress.org page or vendor docs for tested-up-to information. For premium plugins, use the developer’s changelog or support site.
If a plugin has not been updated for a long time and fails with your WordPress version, replace it or contact the author before you rely on it in production. Always back up before plugin updates.
Also keep plugins themselves updated: Check if plugins are up to date.
