I added some custom fields to my new shop with this tutorial:

It was all good for some days when I suddenly got this Error Massage in the Backend:

This happens when I wanted to add a Product or a new Category.
I´m not that good in SQL or PHP.
Maybe someone can help me out?
I would also hire a Freelancer
Thanks
