[Plugin: WP-PostViews] PostViews Count reset after 3.1. update

The problem is not that.
The problem is that he no longer works in version 3.1
Should we expect an update?

I have no idea why it is not working for you, but it is working for me on 2 of my blogs on 3.1 https://lesterchan.net/wordpress/ and WP-PostViews has just been updated last month.

Try the default theme with no other plugins activated to see if it is a theme or plugin conflict.

What plugin do you use for this?
