As per the error, the
PickerHierarchyControl.js is missing in your server.
This file is located at the below path:
C:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\TEMPLATE\LAYOUTS
So as a quick fixe,
- Make sure that you have cleared the browser cache,
- If the issue still exists, I would suggest copying the same file
PickerHierarchyControl.jsfrom another working farm/server and paste it into your farm on the same path!
