Licensing

A MilliCache Pro license unlocks the premium modules and plugin updates. Page caching itself never depends on the license: an expired or missing license leaves everything MilliCache itself provides fully intact.

Activating a License#Copied!

1. Go to Settings → MilliCache → Settings → License.
2. Paste the key from your purchase email into the License key field.
3. Click Activate.

The section badge switches to Active and every Pro module unlocks. Lost your key? It is always available in your customer dashboard.

Once active, the key field is locked and displayed masked (first and last three characters only). The key is stored encrypted in your database and is never exposed in full through the settings screen or the REST API.

Supplying the Key via wp-config.php#Copied!

The key can be defined as a constant instead of saving it in the database:

 1define( 'MC_LICENSE_KEY', '00000000-1111-2222-3333-444444444444' );

The constant overrides any saved key and locks the key field in the admin UI. No manual Activate click is needed: the next license check registers the installation automatically. Deactivate is not offered while the constant is set, since the next check would activate the installation again; remove the constant first. On Multisite, a constant key acts as the network license for the whole install, so subsites ride it just like a key entered via Network Activate.

Seats and License States#Copied!

Your plan includes a number of seats (sites). Activations are checked against millipress.com, and the Status tab always tells you where you stand:

Going over the limit never breaks anything abruptly: you always pass through the grace state first.

Moving to a New Site or Domain#Copied!

Before migrating, click Deactivate in the License section. This frees the activation slot upstream, so you can re-activate the same key on the new site or domain.

If you clone a site (staging copies, migrations that duplicate the database), the clone carries the original's install identity. Give the clone its own identity with:

 1wp millicache license install-id reset

Multisite Networks#Copied!

On multisite, licensing is flexible per site:

• Network key (default): activate one key in the Network Admin License section via Network Activate. Every active subsite uses it and counts toward your seat limit.
• Own key: a subsite can activate its own separate license key instead. Its License section is visible to super admins.
• Opted out: a subsite can be excluded from the network license entirely, running without the Pro features.

Network Deactivate frees the seats of every subsite using the network key and clears the saved key; subsites with their own license are unaffected.

WP-CLI#Copied!

Options:

• status supports --format=table|json|csv|yaml and, on multisite, --network to list every subsite's license mode plus a network summary
• On multisite, activate and deactivate act on the site given by --url. Add --network to act on the network license instead.

On multisite the commands follow the same rules as the admin UI. Activating a site with its own key licenses it separately; activating it without a key puts it back on the network license. Deactivating a site with its own key frees that seat; deactivating a site on the network license opts it out. deactivate --network frees every seat on the network license and clears the key. A site that holds its own key reads as own_key and cannot be switched with subsite-state until it is deactivated.

Examples:

 1# Activate a single site or the whole network
 2wp millicache license activate --key=00000000-1111-2222-3333-444444444444
 3wp millicache license activate --network --key=00000000-1111-2222-3333-444444444444
 4
 5# License one subsite separately, or return it to the network license
 6wp millicache license activate --url=shop.example.com --key=00000000-1111-2222-3333-444444444444
 7wp millicache license deactivate --url=shop.example.com
 8
 9# Check the whole network at a glance
10wp millicache license status --network
11
12# Exclude one subsite from the network license
13wp millicache license subsite-state 3 opted_out
14
15# Attach the network license to one subsite
16wp millicache license subsite-state 3 network

Good to Know#Copied!

• Settings resets keep your license. A full settings reset restores caching defaults but preserves the license key (along with storage and Edge Cache credentials), so you never have to dig out the key again.
• Updates are license-gated. Plugin updates arrive via the normal WordPress update flow as long as the license is active; see Installation.
• Try prereleases on staging. Add define( 'MC_UPDATE_PRERELEASE', true ); to wp-config.php to follow the prerelease channel, and the update flow offers the newest build including prereleases. Leave it out (the default) to track stable releases only. Best kept to a staging site.
• Your key doubles as the Composer credential. Installing via Composer authenticates against the MilliPress package repository with the license key as the HTTP Basic password; downloads require an active license.
• Support snapshots are safe to share. The Status tab's support snapshot includes the license state and seat usage but never the key itself.
