Re: Blank site with shouty
I believe (but can’t recall exactly) that it was 1.1.0 (and so 1.1.1 and 1.1.2) that changed to parent/child theming, so unless a theme explicitly declares compatibility with that revision or higher, you may have issues (which you can overcome if you’re conversant with the way that stuff works). I’ve only just wrapped my head around the child theming stuff (and it’s very cool).
There aren’t many great-looking themes out there for BP yet. If you’re willing to pay, wpmudev premium has a couple, but I wouldn’t say the themes alone are worth the price of admission.
