Laravel Ajax - Put request 500 internal server error

Hi All,

It has been almost a week and still I'm not able to find out the 500 internal server error mystery which is happening only on when the application is on running on a shared server (works perfectly on local machine).

Summary of what i am trying: After creating a Ticket, add n-number of TicketNotes to the Ticket while editing the Ticket. In order to add the TicketNotes I am using ajax CRUD for the TicketNotes. BTW I am using Bootstrap 3 Modal.

I am able to update Ticket but when I try to update TicketNotes it fails on shared hosting, throws this error in console.log. And the best part is GET POST and DELETE all are working only on PUT it's throwing error. Its so frustrating... NEED HELP!!!

Here is my code:

app.blade.php

. . .
. . .

<meta name="csrf-token" content="{{ csrf_token() }}">
