Error to add product

Question

In my admin area when I click on add product, I am directed to a screen with error 500, in my log, I have the following message

"[2020-05-29 14:54:03] main.INFO: Broken reference: the 'product.reviews' the element cannot be added as a child to 'product_tabs', because the latter doesn't exist [] []

What could have happened?

Answer 1

Solution:

Ran the query on my magento database: SELECT * FROM eav_attribute WHERE source_model LIKE "%Temando%"

Set the 3 values to "NULL".

Now I can edit products again.
