Activating a license key

After you purchase an extension you’ll receive a confirmation email with a license key that looks like TCX-ABCD1234-EFGH5678-IJKL9012. You activate it once per site; the activation tells our update server that this extension is allowed on this domain.

Find your license key

Three places to find it:

• The purchase confirmation email.
• Your account page at market.titancart.io → My Licenses.
• The email receipt from the checkout, which has the key inline below the order number.

Activate on your site

1. Make sure the extension is installed and activated as a WordPress plugin. If you haven’t yet, go to Plugins → Add New → Upload Plugin and upload the ZIP.
2. Find the extension’s settings page. Most extensions add a menu entry under TitanCart → Extensions → [Extension name], with a License section at the top.
3. Paste the license key into the License key field.
4. Click Activate license. TitanCart pings our license server and you should see a green confirmation with the license holder’s email, the expiry (if applicable) and the site slots used vs. total.

What “active” means

An active license grants three things:

1. Extension functionality. Some extensions gate their features behind an active license check and stop working when the license lapses. The setting is per extension.
2. Automatic updates. The site shows update notifications in the WordPress plugin list when new versions ship.
3. Priority support. License holders get faster ticket response times from our support team.

Multi-site licenses

Most extensions are sold as single-site by default, with multi-site packs available at a discount (usually 5 or 25 sites per license). The site slot is allocated when you activate the license on a site and returned when you deactivate on that site.

To move a license from site A to site B:

1. On site A, open the extension’s settings page and click Deactivate license. The slot is freed immediately.
2. On site B, paste the same key and click Activate license.

Deactivating a license

If you’re taking a site offline, selling the business, or moving hosts, deactivate the license before you remove the files. That way the slot is returned to your account and you can use it on the new site without contacting support.

Troubleshooting

“Invalid license” error. Double-check the key has no leading or trailing spaces. Try re-copying from the confirmation email. If it still fails, the license may have been revoked due to a refund — check your account page.

“Site limit reached” error. You’ve used all the site slots on this license. Either deactivate the license on a site you no longer use, or upgrade to a larger pack from your account page.

“Unable to reach license server”. Your host is blocking outbound HTTP requests to market.titancart.io. Ask your host to whitelist it, or check whether a security plugin (Wordfence, Sucuri) is filtering the request.

Updates stopped appearing but the license is active. Clear the WordPress update transient with a plugin refresh — go to Dashboard → Updates → Check again, or deactivate and reactivate the license.

Renewals: because extensions are one-time purchases with lifetime updates, most licenses do not expire. A few flagship extensions (Subscriptions, Multi-Vendor) offer optional annual plans that bundle priority support and faster release cadence — those do renew annually, and your account page shows the exact expiry date if so.
