i cant make my apps work
That doesn’t actually mean there’s anything wrong; it simply means that there is no web-based configuration page for them - hence the “Not Available”. “Fuppes” is the only DroboApp I’ve found with a web-interface, all others show the same as what you’re seeing (but they are working).
Some DroboApps don’t require configuration; some require you to poke around with the config files yourself.
I hope that clears things up.
