We took a backup of production site and restored it on our development server. The restoration process went fine with no errors thrown.
But when we try to save item in any list the console throws error that:
PreSaveItem is not defined
It seems that the library where PreSaveItem function is defined is absent. But I am not able to pinpoint anything over here. Any possible leads on how should this problem be approached? Anything we can make sure to verify that the restoration process was error free?
