Why Is My License Key Invalid? ​

There are several common reasons why a license key may show as invalid. Below are the most common causes and how to resolve them.

Your Subscription Has Expired ​

Most Themeisle subscriptions renew on a yearly basis. Once your subscription expires, your license key becomes invalid. To check your subscription status, log in to your ThemeIsle account and review the My Products tab.

If your subscription has expired, you can manually renew your plan to reactivate your license key.

You’re Using an Old License Key ​

If you renewed your subscription using a different email address, or if your subscription was manually adjusted by our support team, you may have received a new license key. The old key will no longer work.

To get your current license key, log in to your ThemeIsle account and check your active products. Your current license key will be displayed there.

License Key Character Limit Error ​

Some older products (such as Robin Image Optimizer) were previously managed through a different licensing system (Freemius). If you see an error about the license key being limited to 32 characters, this means you need to update to the latest version of the plugin that uses the Themeisle licensing system.

To resolve this:

  1. Deactivate and delete the current version of the plugin from your WordPress dashboard.
  2. Download the latest version from your ThemeIsle account.
  3. Install and activate the new version.
  4. Enter your Themeisle license key when prompted.

License Key Not Recognized by the Plugin ​

If your license key is correct but the plugin doesn’t recognize it, try the following:

  1. Make sure you’re entering the license key for the correct product (e.g., a Neve Pro key won’t work for Otter Pro).
  2. Check that your website domain matches one of the sites registered to your license. See How to manage your website licenses.
  3. Try deactivating the license from your ThemeIsle account, then reactivating it on your site.
