A customer had php version set to 5.4 FPM but that had been disabled at the Plesk global level. Trying to access hosting settings or php settings at the domain level produced:
ERROR: Method Smb_Form_Final_Web_Settings::__toString() must not throw an exception, caught Error: Call to a member function getId() on null (settings.phtml:0)
Had to turn 5.4/FPM back on to get access to that page to change their php version before turning it back off.
