I figured out why it happened now. [Advanced ads] plugin, caching busting featured. once its turned on. It will break your view counter.
If I wasn’t it shouldn’t working previously. How should I check it?
I have been using it for a while, it only shows -1 after the recent update. Is it related to my cache plugin?
Looks a bit too complicated. Could we simplify it and produce a more easily executable solution?
