Post counts by days stop working

Hi,

I’m using the plugin to show posts by max counts for the current day. I use this code:

global $wpdb;
$table_name = "{$wpdb->prefix}post_views";

$results = $wpdb->get_results(
	"SELECT id FROM $table_name WHERE period = CURRENT_DATE()  ORDER BY count DESC LIMIT 4"
); 

Before the latest update everything was working fine. However after the last update I’ve noticed that the fields in the database with type 0 are not updating. However the overall views are.
