Hi 2bruce2,
It must show the post id, There is only a one way to activate slider in free version. i think its due to the plugins you have installed. Once deactivate all the plugins and check it whether it works or not.

Also to view the id you go to the dashboard -> settings -> permalink -> select default.
So that you can also have the id of the particular page / post

Thank you!
