I don't know if you have figured out this issue or not being it was a couple months ago when you asked the question, but I came across this same problem and it had to do with with other plugins conflicting with it, so I will post the solution for future inquirys.
Probably a namespace conflict, simply do this...
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.
