If you keep getting License Error Message then follow the steps below:

1. Make sure you have added valid domain/website from Customer Panel. The domain should not contains www. For example, it should be example.com but not www.example.com
2. In Admin Panel under Configurations, make sure that the value for SITE_ADDRESS and SCRIPT_LICENSE_KEY is correct.
3. If you are still having same issue then, try re-saving the value for SCRIPT_LICENSE_KEY with the correct License Key and it should be fixed automatically.
