BuddyPress.org

I hope I’m right in saying the last issue I face, aside the css, is the upload permissions. Apache doesn’t seem to be able to create folders so if I want to upload an avatar or document I get:

Upload Failed! Error was: Unable to create directory wp-content/uploads/avatars/6. Is its parent directory writable by the server?

I’ve checked all my folders; buddypress theme pack, uploads etc and all is set to 755. If I set wp content to 777 everything works as it should. I know this should work with 755 though. Any ideas please?
