I am new to WP. I am not a techie and I don't code. I down loaded "My Post Order" and desperately tried to make the most rudimentary change to my post so that the post would show the oldest first and continue down to the newest last....nothing.
Nothing that you said could be done worked. Am I really supposed to be a code writer to do something this simple? When I buy a car I expect that it will go into reverse also.
