Scroll not working

Common issue, but I can’t get my page to scroll… I have checked all elements and think they are all set to overflow, but one must not be. Inspecting the code there is something showing as Hidden.

Also, with this FAQ setup, using pagination there is no connection between URL and the content, not sure how to make a connection between the two.; is it possible?
