I advise you not to use that version because it is still under development and you cannot play with a version under development because the code is not complete, do you use the nulled version for testing or for production? nulled versions are not good for running them in production, so I recommend that you buy the original version if you want to run in production, or you need to update manually if you are a developer. You cannot ask for support in a nulled forum for a theme not compatible with XenForo version 2.2 candidate, it will never work, you will have many problems in the future!
I am a web developer so I know these things
