Dear kuller

Please set Error reporting to None in Global configuration -> Server tab.
or Could you please let us know your Item Purchase Code of this theme? You can refer guide in here: www.smartaddons.com/documentation/how-to-get-themeforest-item-purchase-code/

We need to check it before supporting. then send us the admin and ftp account to check directly.

thanks
