BuddyPress.org

hi Donnacha

Let me clarify first.

It is not the case.the bleeding version of Buddypress can be installed from the downloaded archive from

https://trac.buddypress.org/browser/trunk

I have done it successfully on my local windows install(I run your great work wpmu on my local windows for testing )

Please try uploading a stable release of buddypress in wp-content/plugins and see ,if it is appearing ?

If not,then must have something to with the server,

If yes, then further investigation will be required,may be a word from Andy or someone who has done it on Mac will be great.
