errors themeforest go explore

I use themeforest go explore and i have error with these pages:

These pages with errors are available in “Pages” section on blog dashboard, but when i click to preview them by clicking “View” link underneath page name, they are not available.

More than that, if I want to create a new page or to modify the content of a page already created, then it happens the same error explained above.
Please check, it is very important your support!

Theme-specific issues need to be addressed by the author.

However - you have no buyer badge on your account. You need to log in using the account which bought the theme so that the author can validate the purchase before providing support.
