I just migrated an Akeeba Backup archive to my staging server for testing. Everything seems to be working, but upon opening AdminTools > Web Application FIrewall, I experience this:
Admin Tools for Joomla!- An unhandled Exception has been detected 500 Layout default not found.
File <root>/libraries/src/MVC/View/HtmlView.php
Line 425
The content below this point is for developers and power users.

There are pages of details. I went back to the other server, and tested the Web Application Firewall. It was fine. I created a new Akeeba Backup, and tried the migration again, but I get the same error.
