I see two errors basically – one is related to revolution slider over which I have little control.
The second one is related to prettyPhoto plugin. Let me try to fix this in upcoming update. It should cause no harm IMO and have been ignored by developer community for long, including the Themeforest reviewers. We have fixed this for our later themes as per instructions here on using hook attribute of PrettyPhoto plugin.
