Thanks @ikuko-k, that’s strange that the error is still complaining about WordFence. Try going to your /wp-content/plugins directory on the DevKinsta site and delete/rename the WordFence directory. What I see from the error in your error.log is that something is trying to load wordfence-waf.php using the path from from MyKinsta instead of DevKinsta.
I’ve seen WordFence do thisa few times before like here: Imported Kinsta Site Blank - #3 by anthonynickerson
