On a typical multisite system, each individual site has its own database. Did you update the others and forget to update this one?

Or, if you haven’t updated the others, perhaps you just didn’t trigger the issue on any of the other sites yet. Regardless, go update them now if you haven’t!

The root cause of your error appears to be that the code expects a database table column that is not actually in your database. Did you update your code (either core or contrib modules) recently? You may need to invoke update.php.

Try pointing your browser at [your site]/update.php and see if any updates need to be performed.

If that is not the problem, is there anything in your status report? (Navigate to Reports -> Status Report or point your browser at /admin/reports/status).
