You must contact author for support, this is general forum.
As of many PHP requirements could be a problem with end-users and their hosting, not really an acceptance factor here on Themeforest.
The most important factor here is licensing. This framework seems to use GPL so it’s alright.
This is not support forum, you can use sites such as stackoverflow to ask questions.
Or download it and read the license info.

Try to bring something new to the design community, don’t just try to do what works.
The best way to solve item related issue is to download all materials, not just the theme. Find the documentation in the main package, and then if the situation is not clear, contact the theme developer for clarification.
This is due to new Envato API changes developing as we speak.
