Some of my admins are seeing SQL errors

That looks like some of the Admins don't have user ID's assigned and that wouldn't make any sense.

If you made modifications to the code, find that file putting the error and figure out what you did. You may have removed a condition or something.

But do as suggested above but also check the users table and see if those admins have a null value for the user id... that shouldn't make sense because they are primary keys, so it must be that someone removed or added a syntax error in the code.
