Error in error_log Recurrent on and off

I have disabled plugins still get errors, Switched themes still get errors. I have made a ticket and it’s been on going and they are not helping me, Seems that Well it’s not erroring now so I’m going to ignore you ticket until you jump up and down then make it like I’m helping you.
I’m really sick of the non support with this theme.
Same thing happens on another site with this theme.
I had the same error before and that ticket is still open. Now it’s Back.
the other ticket is from 28 January 2017 06:22 PM I asked to forward to the developer that never happened
I went to chat with maria on Feb 3rd 2017 said that mark will look into this after the website maintenance was over. That never happened and you wonder why this company gets bad reviews.
Now foward to today: I’m not letting up on this I have proven its the theme and others have had the same or similar errors.

Here’s the current error

[28-Jul-2017 13:51:14 UTC] WordPress database error Unknown column
