Post views counter is not visible

WordPress doesn't count views for posts by default so we need to use 3rd party plugin for that. To display post views, please install and activate the Wordpress Popular Posts plugin. Then go and visit one of your posts to increase its views counter. Now you should see current number of views for that post.

Set up views threshold

By default the theme doesn't show views counter if there is less than 10 views.
You can of change that setting in the WordPress Admin › Appearance › Customize › Posts › Global › Hide views section.
