Hi,
On ThemeForest we’ve put info is compatible with magento 1.9.0.1. Maybe it has issue when update to magento 1.9.2.0. So, you should use magento 1.9.0.1.
If you still want use magento 1.9.2.0 and get error then please tell me more detail about your issue, maybe we can help your with each issue
Thanks!
