Yes. The paleolithic diet excludes grains for the reason that it was not included in the Stone Age human's diet. If Stone Age humans did have refined starches in their diet, then if you wanted to follow a truly paleolithic diet you would eat flour. Of course, I never bought the diet to begin with for totally different reasons, which is that 10,000 years is plenty of time to adapt to a new diet. I prefer the pre-industrial diet. It's obvious that fast food is bad for us, it's not obvious that pasta is generally evil.
