If you can find no change in your screen, it is convenient to immediately check whether it is due to a transient or a bug.

Purgify – Transient Purge gives you a fast, accessible way to clear WordPress transients without leaving the screen you’re on.
<h4>Features</h4>
<ul>
<li>Admin Toolbar menu — clear transients from any admin screen or front-end (if logged in as admin) with one click.</li>
<li>Settings page (<code>Tools → Purgify</code>) — dedicated page with both clear actions and documentation.</li>

<ul>
<li>Clear All — removes every transient regardless of expiry.</li>

<li>Translations ready — ships with translations for Spanish, French, German, Portuguese (Brazil), and Italian.</li>
