Hi, there. Theme developer here. Sorry for the late reply. Didn’t even know this support forum even existed.
Anyway, if you are still using the theme and having any problem, feel free to send me an email, hendra2392 at gmail for immediate help.
I am planning to add better support for custom menu and plugins. Making it responsive is also on the table, but I can’t find time for working on them yet as I am busy dealing with exams, but I promise they are coming.
