Please check if this site http://www.pixelsheriff.com/ is legally using your template because i would like to use their services
Hi,
Thanks for contacting us!
Many agencies purchase separate license for their clients and provide them their purchase code (which you will need to register to our support forum – https://kriesi.at/support/register/ ) and they provide ThemeForest username and API key – kriesi.at/documentation/enfold/updating-your-theme-files/ so you can receive auto updates from your WordPress dashboard.
I believe they are doing the same. You can contact them and ask if you will have your own license and receive the information i mentioned above or not. Alternatively, you can purchase the theme here – https://themeforest.net/item/enfold-responsive-multipurpose-theme/4519990?ref=Kriesi and use their services. In that case you will have access to theme files on your ThemeForest account.
I hope that was helpful! Let us know if you have any other questions :)
Cheers!
Yigit
