Fabrik 500 Error on Site

[Parisi]

I am receiving a SQL error as a 500 error on first load of a site running Fabrik. It is shieldbyplg.com. Refreshing often causes the error to disappear. I have uploaded the site information under "my sites" and I have put the full error in the "notes" for that site, since I do not want to list actual table names here.

Please advise, I'm at a bit of a loss here of even where to start looking to fix the error. This was not appearing as recently as a week ago. As far as I know, no structural modifications to tables have been made by site admins in that time.

Update: I believe the issue has been resolved, some (old) elements were still published that were related to columns that (now) do not exist. I will close the ticket later if the solution seems to have worked and re-update if not.
