Hello, CB Profile Pro and CB SUBS are perfectly compatible. CB SUBS is an amazing component, the only thing that's missing, in my opinion, is the possibility to customize user profiles and to change edit and registration pages. CB Profile Pro lets you do just that, while there is still a bug in CB Profile pro regarding registration pages. In this regard, I say to joomlapolis staff to seriously consider the possibility to integrate cb profile pro in cb subs or to develop something similar, because, I repeat, is the only thing missing in CB SUBS.
