Error in plugin

Our plugin is configured to display popular posts visited within last 7 days. It worked fine up until recently. It looks like the database column name has changed and the query can’t access the right column anymore.
Here’s the error produced on the website:

WordPress database error: [Unknown column ‘v.view_datetime’ in ‘where clause’]
SELECT p.ID AS id, p.post_title AS title, p.post_author AS uid FROM wlg_popularpostssummary v LEFT JOIN wlg_posts p ON v.postid = p.ID WHERE 1 = 1 AND p.post_type IN(‘post’) AND v.view_datetime > DATE_SUB(‘2017-10-18 11:10:08’, INTERVAL 6 DAY) AND p.post_password = ” AND p.post_status = ‘publish’ GROUP BY v.postid ORDER BY SUM(v.pageviews) DESC LIMIT 10;

Sorry. No data so far.

When I inspect popularpostssummary DB table, there is no view_datetime column, but there is a last_viewed column now.

Could you please fix?

Thanks!
