Why doesn’t my license key work?
A license key is no longer needed to use our premium plugins because we launched a customer portal where you can find and manage all the Yoast SEO products you own. If you don’t have an account yet or want to know how it all works, this guide will get you started.
If your plugin version is below 5.2, please manually update to the current version to activate your subscription.
If your plugin version is between 5.2.x and 5.4.x, please enter a 0 for the license key to force the plugin to switch to our new customer portal under SEO -> Premium.
