You just need to update to the latest version of the plugin and then you will be able to show social media buttons on the top of the post.
You can also use the shortcode [social] to show social share buttons anywhere on your website.
By default this plugin’s functionality has been disabled for homepage/frontpage/archive/search page and for the 404 error pages. More options will be added very soon.
In case you don’t want to use this plugin you can read my article on how to add social share buttons without plugin.
This tutorial will require you to edit your theme’s function.php file.
Styles are also provided so you just need to copy and paste them in your style.css file.
If you have any more questions, please let me know.
Thanks.
