Help on Real 12

I'm stuck on realistic 12, and am not sure what I'm suppose to do next. I've made in past the protected folder and am now at the admin panel with the key, and no idea how to proceed from here.

Do I recall corectly that when you use smth with that include it used to give some errors and now not anymore? And Thucydides there is an answer in forum in topic which is old.

Ok, thanks, I beat the mission. At least one of the ways that the mission can be beat, I'm still not sure how to get past the admin panel.
