Since WordPress doesn’t track views by default this had to be a plugin.
This is the Yuzo ̵ ̵ ̵ Related Posts plugin. The reason you were seeing 0 for views is because when you first click on Posts you’re looking at All posts which just so happen to have Drafts at the top at the moment that have never been published, therefore wouldn’t have any views yet.
Simply click on Published and you’ll see your view stats are still working.
Additionally, it looks like you have 3 Google Analytics plugins installed. You should choose just one and remove the others.
