Error message in admin

The following message is always at the top of my dashboard now:

Warning: in_array() expects parameter 2 to be array, null given in /home/*******/public_html/wp-content/plugins/content-views-query-and-display-post-page/admin/content-views-admin.php on line 431

I’ve only removed the domain as it’s a private site and not open to the public.
