“No data so far” after update

Hello,
after updating the plugin to the latest version, I got the famous Sorry. No data so far. problem.

I tried to hit the “Delete cache” button, no luck. In the admin, I don’t see any data, but in the wp_popularpostsdata I can see all the view counts, and new views are recorded correctly.

I also tried to disable WP Super Cache completely (the plugin used to work with the Super cache enabled though).

The Debug tab is:
