To enable php display errors, please go to file : app/bootstrap.php and uncomment the line ini_set: ('display_errors', 1);

Try loading the URL in the browser again. See what you get. That should be enough in your case.

Remember to undo your change after.

  • @VishwasBhatnagar If he loads the URL that is throwing 500 this is an answer. The question was Any help? Jun 6, 2019 at 11:58
  • Solution of error that is displayed on tha URL , would be the actual solution to answer in my opinion . Debugging is identifying the problem not a solution . Jun 6, 2019 at 12:01

    @VishwasBhatnagar Semantics. Identifying a problem is working towards a solution. And again, the question was Any help?. I think that's open enough for this answer. Jun 6, 2019 at 12:03
