Product License Activation
Activating you purchased product license key is necessary for enabeling the automatic updates via WP dashboard.
To activate the license key click the Settings link under the plugin name or the link to the plugin settings page under the Plugins menu item (for example, Divi DotNav, Divi ScrollTop, etc.).
Both of these two links point to the same settings page with the license activation form.
To activate the license key first copy it from the Purchase Receipt that has been sent to your email address immediately after completing the purchase or log in to your Divicio.us account and go to Purchase History -> View Licenses.
Then click the small key icon and copy the license key.
After copying it go back to the license activation form, paste the key into the license key field, click the Save Changes button and finally click the Activate License button.
The green active word indicates that the license has been successfully activated.
