Viewing posts is very strange. In Firefox, Google Chrome, and Opera browsers, updating a post page or opening a post does not increase the number of views. It only works when you press ctrl + f5 and only occasionally.
There is no caching on the site. There are no caching plugins.
My plugin settings:
Post Types Count: Posts
Counter Mode: PHP (also tried Fast AJAX)
Count Interval: 1 min.
Reset Data Interval: 0 days
Flush Object Cache Interval: 0 min.
