@mercime – I’ve deleted define ( ‘BP_ENABLE_MULTIBLOG’, true ); from bp-custom.php, but now the plugin doesn’t show up in any of my subsites.
My BP install is on example.com/socialnetwork, and I have 40 other blogs like example.com/blog1, example.com/blog2 etc. I only want BP to “show up” on the BP blog.
