My themes are also deactivated. I also have Frisco and it is now in the “corrupt” templates — it requires bp-default theme, so I think it cannot find it by the old address. What should be done to recover it?
Incidentally, I finished the translation, but it is in developing mode. No problem, though, I can use it on my own, I just need to understand, what to do: download a .mo file, rename it to something and place in bp-languages? What name should it have to work?
