I can’t see how setting the front page back to showing blog posts should be broken by 1.5. All this works fine for me on my test installs (admittedly a new install, not an upgrade).

@tmcneill71 You can grab older versions from https://wordpress.org/extend/plugins/buddypress/download/

@mikepratt, Tim: What other plugins are you running. What theme. Multisite – if so, subdomain or subdirectory? Prior to upgrading, what did you have your home page set as, or was it just showing blog posts?
