Many thanks for plugin.
wp 3.5, bp 1.6.2 child theme of bp default.
Single site install -everything works.
But on a multisite local install the "add task" tries to open but just doesn't.
I May be incorrect (some plugin conflict maybe) as i haven't tried it on just the default theme and nothing else. But the single site install would have had all the plugins that are on the multisite activated and collabpress did work.
