Activate your POM Cache license

POM Cache uses the common POM product-license system. The license connects the WordPress installation to an active subscription, authorizes its domain, and enables private downloads and automatic updates.

License validation is deliberately separate from cache delivery. A temporary account-server outage must not stop POM Cache from serving, writing, or invalidating origin cache files.

Understand the subscription

POM Cache is provided through a renewable zero-price subscription:

• checkout is still required;
• the subscription must remain active;
• a license key is issued through the POM account;
• each installation domain must be authorized;
• private releases remain license-gated.

The POM Cache subscription uses the UNLIMITED plan, so it is suitable for single sites, multisite networks, and multiple authorized domains. “Unlimited” does not mean “unlicensed”: every installation still follows the normal key and domain-validation flow.

Before activation

You need:

• administrator access on a single-site installation, or network-administrator access on multisite;
• access to the POM account that owns the subscription;
• the final site or network domain, not a temporary value that is about to change;
• outbound HTTPS access from WordPress to the POM account service;
• the official POM Cache installation active, or network-active on multisite.

Complete the installation checks first. The license can validate even when HTML caching is still disabled.

Save and validate the key

1. Sign in to account.pom.es.
2. Open My Account → Licenses & Downloads.
3. Copy the POM Cache license key.
4. In WordPress, open Settings → POM Cache → License on a single site, or Network Admin → Settings → POM Cache → License on multisite.
5. Paste the key into the password field.
6. Select Save and validate.
7. Wait for the confirmation: License validated. This domain is authorized.

After saving, WordPress displays only a masked form of the key. The status panel can also show the license state, plan, expiry, and authorized domain.

Do not include the key in screenshots, documentation, tickets, chat messages, browser URLs, or logs.

License scope

On a single-site installation, POM Cache stores one product license for that WordPress site. It authorizes the site domain and allows the common updater to request private release metadata.

On multisite, POM Cache uses one network-scoped product license. Configure it from the network administration so the common updater can detect new versions for the installation.

Individual subsites do not need separate POM Cache keys. Their cache files and current-site settings remain separate, but private plugin updates are a network-level concern.

If an update is not detected, confirm that POM Cache is active and the relevant site or network license is valid. On multisite, also confirm that it is network-active or active on the main site.

Manage an existing license

The License section provides three safe actions:

• Revalidate checks the stored key and current domain again.
• Replace and validate validates a new key before replacing the working stored key; a typing error does not discard the previous connection.
• Unlink asks the account service to deactivate the domain and removes the local key only after a successful response.

Copying or rotating the recoverable key is performed in My Account, not in WordPress.

Use Unlink before permanently moving the installation to another domain. A routine plugin update, cache purge, or CDN change does not require unlinking.

If validation fails

Work through these checks in order:

1. Copy the key again from Licenses & Downloads; do not type it manually.
2. Confirm the subscription is active, even though its renewal price is zero.
3. Confirm the current WordPress domain is the one that should be authorized.
4. Review authorized domains in My Account.
5. Confirm WordPress can make outbound HTTPS requests.
6. Retry Revalidate after a temporary network problem.

If WordPress reports that the stored license cannot be read because site secrets changed, paste the key again and use Save and validate to reconnect it.

When Unlink cannot reach the license service, the local key is intentionally kept. Resolve the connection problem and try again rather than deleting local data manually.

What happens during an account outage

POM Cache does not perform remote license checks in:

• advanced-cache.php;
• Apache or PHP cache hits;
• HTML or JSON writes;
• manual or automatic invalidation;
• ordinary frontend requests.

Cached pages therefore continue to work. Operations that genuinely require the account service—fresh validation, domain unlinking, update metadata, and private downloads—may need to wait until connectivity returns.

Continue with the POM Cache interface tour before enabling the first page.
