Rule set 4 will overlap with rule set 1 and 2. I suspect this is causing the issue. So I think all 3 need an extra RewriteCond check on REQUEST_URI .
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.
