You said: I’m really, really relieved. And I hope that my results will help others. I don’t know if the issues I encountered are related to BP and WPMU running together, or with WPMU itself, or with BP, or all of the above. But since my installations were broken in a subfolder, I believe that a subfolder installation of the social network should be avoided.
It is still available? Because I’ve installed in a subdir and almost everything is OK, but new blogs from users go in to mydomen/wpmu instead of mydomen/wpmu/blogs You can checl here http://ciprianalexa.ca/wpmu/
I’m thinking to install the wpmu+buddy in the main root, but want to double check if ti works in subdir.
