Error while sending QUERY packet

I saw this error messages more than once

Warning: Error while sending QUERY packet. PID=137086 in /home/xxx/public_html/couponat/wp-includes/wp-db.php on line 1877

And

Warning: array_map(): Argument #2 should be an array in /home/xxx/public_html/couponat/wp-content/plugins/ultimate-wp-query-search-filter/classes/uwpqsf-process-class.php on line 53

Can you help me or update this plugin to the latest version? I can’t forget the donation if this issue solved ??
