The theme "Parrot" can't install but it is. It is unable to activated over WPMU Dashboard but over WP themes dashboard is activating possible.
It's not a problem with folder permission etc.
Maybe its a wrong flag in database that I can not find.
Anyway, it's unable to install, and update if comes up. The WPMU dashboard don't know thats "Parrot" is already installed.
Please log in and see what happens.
Dashboard support login is openon "aaki.de" !
Thanks you and
