That error is usually the result of jQuery framework not being installed. It looks like your jquery. Js is your jQuery framework since you mention your not using any custom markup yourself.
You should include jquery in all controller/action, to do that, insert this code to Controller. Php (most parent of all controller in application).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
