Ava working again?

Well, I was opening the reactor and I still got the same error, the xml error, so i thought lets visit ava.ijji but, then it took me to something strange, where u gotta delete default.php in public.php folder, how does this actually, work? where is that folder? and how to play ava with reactor again?

Re-Install the reactor
