Houzez Purchase Verification
Enter purchase code to verify your purchase. This will allow you to install plugins, import demo and unlock all features
Enter item purchase code.
You can consult this article to learn how to get item purchase code or you can purchase new license from themeforest which will include 6 months free support and lifetime updates.
