Plugin: WordPress Popular Posts: Sorry, no data so far

Hello.

My site have been up for a few days now, and every post have been viewed multiple times.

The plugin still says Sorry, no data so far.

What can I do to resolve this?

Plugin is updated
Theme has “<?php wp_head(); ?> </head>”
There are rows in the database, but they seem to be empty.
Settings are: order by avg. daily views
Widget setting: avg. daily views, filter: posts, 30 days.
