I installed stuffplug-NG a couple of weeks ago. The first tim that a user loggs in with a new email, a window appears and asks if he'd like to enable all the features. I did that the first time that it appeared, but know, even though in the options the plugin seems to be installed, the features that I had enabled don't seem to work. Maybe i changed smth without noticing it. What can I do about it?
