Sorry, you have reached your activation limit for this license

If you deleted plugin data or you changed site url (e.g. from http to https) without deactivate license before, the license activation counter keeps in one (or three), that’s your license activation limit.

To solve the problem, Go to My Account → Licenses, click on “Manage sites” and delete current site. After doing so, you will be able to activate your license again from: Your site → wp-admin → WooCommerce →Settings → Zone Pricing → License.
