I have a magento 2.1.2 install. I have used the data migration tool to migrate a magento 220.127.116.11 setting and data as per this guide.
I am getting the following error message on a couple of pages when I try to navigate to them in the backend.
Class Magento\Framework\DB\TransactionFactory does not exist
I get this when trying to go to Content --> Design --> [my store] --> edit
I also get it at Stores --> Configuration
These are the only two I have found so far.
Can anyone shed any light on what this might be? I am guessing it might be an extension that is missing?
