Plugin stopped counting views

Hi there,

I noticed that the plugin only showed comments, but no more views withing it’s dashboard. After emptying it’s cache I now got the “Sorry. No data so far.” message and no new data seems to be gathered (even though I emptied my cache and tried the ajax option). WordPress core and all plugins are up to date.

Looked into phpmyadmin and saw, that “wp_popularpostsdata” only got new data until June 1st (stats in the plugin dashboard are all “0”, except for “Hall of Fame”), “wp_popularpostssummary” is empty (well, except for the table column names “ID”, “postid”, “pageviews”, “view_date” and “view_datetime”).

I kind of have no clou why this before fully functional plugin stopped working, maybe you have an idea?
