Adminify has a lot of potential with great features and modules, however still needs a lot of bug fixes and a QA team to catch all small issues. I agree 100% with Whitney Lee's review. Their support is nice and responsive, however, I am too afraid to use this plugin on client sites at the moment.
The question is, will they fix all major issues before the refund period is over? Not sure.. let's see, I truly hope so.
