Upgrading from 18.104.22.168 results in class CategoryTreeNodeKey does not exist
On the old machine I backed up the DB and copied the entire folder to another folder, and tried to update it. To get to version 8, it appears I need to first get to 22.214.171.124 (12-16-2016), right? Somehow throw this process, I now get the following error when attempting to access either the front or logon page.
An unexpected error occurred.
Class \Concrete\Core\Permission\Key\CategoryTreeNodeKey does not exist
I went back to my "copied" backup, but get the same error???
Any recommendations? Thanks!!!
