Clear caches from the administration bar

The POM Cache administration-bar shortcut is the quickest way to remove both generated response stores for the site you are currently viewing.

What the shortcut clears

Select Delete Cache in the WordPress administration bar to delete:

• static HTML cache for the current site;
• progressive JSON cache for the current site;
• the stored status summaries so the next view reflects the new state.

It does not clear another multisite site's namespace and does not invalidate a browser or CDN cache.

This shortcut is broader than the Delete Cache button inside Cache tools, which deletes HTML only.

Who can see it

The shortcut is available when:

• the WordPress administration bar is visible;
• the user is logged in;
• the user has permission to clear site cache.

It is intended for authorized administrators and editorial users who can manage other authors' content. Exact visibility can vary with WordPress capabilities and site policy.

The item appears on both the frontend toolbar and eligible administration screens. On mobile, it is represented by the cache-update icon even when the text label is hidden.

Clear the intended site

1. Visit the frontend or dashboard of the exact site whose cache you want to remove.
2. Confirm the hostname and, on a subdirectory network, the site path;
3. Open the administration bar;
4. Select Delete Cache;
5. Wait while the icon indicates the action is running;
6. Read the returned message.

A successful action reports:

HTML and JSON cache deleted for the current site.

If deletion is prevented by site configuration, POM Cache reports an error rather than presenting the clear as complete.

When this is the right control

Use the administration bar when:

• both the initial page and later progressive batches may be stale;
• you changed a shared template, navigation area, or global display setting;
• you are viewing a specific multisite subsite and want an unambiguous current-site clear;
• an editor needs a simple post-publishing refresh;
• you want one action before coordinated CDN invalidation.

Use the settings tools instead when only HTML or only JSON needs deletion. Keeping the current store preserves warm responses and reduces regeneration.

Verify the result

1. Open POM Cache → General for the current site.
2. Check Cache Contents and Progressive JSON Cache Contents.
3. Confirm both show zero files immediately after the clear;
4. Request an eligible public page directly from the origin;
5. Confirm current HTML and allow it to regenerate;
6. Trigger a progressive batch and confirm current JSON;
7. Repeat both requests and verify the intended hit path.

If the settings summary does not correspond to the site you cleared, recheck the current blog context, hostname, and network location.

CDN and browser state

The toolbar action reaches POM Cache at the WordPress origin. A fast public request can still be an older CDN or browser response.

Use this order:

toolbar clear
→ verify origin HTML and JSON
→ invalidate only affected CDN viewer paths
→ verify public URLs

See Decide when the CDN must also be invalidated for the decision, and Clear HTML and JSON independently if only one response type is stale.
