shortcode

we have this working on a demo site just fine with 3.5 , we installed on another site 3.5 and does not work, we have used default theme and deactivated all other plugins with no help. it seems as the shortcode is not being processed. this is the one that does not work https://www.permittestpractice.com/ca-california/california-permit-test-flash-cards/

no errors found, shows text below shortcode..

Thanks
