Like button not displaying for classified ads

Hi,

I used WPadverts plugin to create a classifieds website, in which i would like to add the like button for the products, so that users can know how many have liked the product. But , even after setting,Automatic Display Restriction-“Singular”? and Post Types Filter -“Posts””Classifieds”. I am not able to see the like button under classifieds. Is there any other settings or change that i need to make , please help me resolve this issue.
