Sounds and looks as though the WP installation already has CSS styles for the class of "breadcrumb". It's a commonly used class name. To fix the problem, either rename the class to something more bespoke e.g. "thisIsMyBreadcrumb".
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.
