We'll create fresh WordPress site with Post Like installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Post Like is a plugin for blog authors that allows you to add like button at the end of single post. User should be logged in to like the post, once post is liked it is stored in user liked posts. User can also unlike the post. In the future release we will add a login link for users who are not logged in and some customizer options. Future releases will also include some of widgets for most liked posts and a user widget to show user liked posts.
When the users are logged in, they will be able to see the like link and counter at the bottom of the single post. Then they will be able to like the post.
After a post is liked by a logged in user, he can also unlike the post after page is refreshed.
For plugin settings go to Settings -> Post Like Settings.
