Subscription Error

[rcull]

I just got a repeated error related to a subscription. It appears to have happened 10 times. Can someone give me some guidance?

The error in the error log is:
[30-Nov-2017 02:00:39 UTC] PHP Warning: mysqli_query(): (42000/1064): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE userid = 25275 AND
subscriptionid = 1' at line 6 in /home/teambuic/public_html/forums/includes/class_core.php on line 1394

I also received an email notification:
Database error in vBulletin 4.2.3:

On the Script line it shows http: where the site is https:. I thought everything was updated probably not a related problem.

Thanks
