https://github.com/mustafaramadhan/kloxo/commit/88eeec1c26ab434e774cac7875c982da0b6970da so in a week or so it's 1 month since last commit.
Unfortunately, this is the consequence of relying on one mans work. Mustafa has put down an enormous work to bring us this awesome web panel, but at the same time, such thing can happen since this is not developed as a community.
In other projects, community has fork the work of Mustafa and further work on it if anyone is brave enough and has the right skills (PHP/JS/CentOS).
The only alternative IMHO today to Kloxo-MR is VestaCP, but it's severely limited by features and functionality.
Kloxo-MR simply rocks as it's a complete web hosting panel.
Would be sad if i and others are forced to jump over to an alternative if this project comes to an end.
