"Illuminate\routing\Controller" there have one mistake routing to Routing . Its replace in "use Illuminate\Routing\Controller" . Hope that it will be works.

Step 1 - check your laravel log file to see more details and call stack Step 2 - check your routes file to see if you try to use "Controller" classes without importing the namespace correctly Step 3 - try different types of composer dump-autoload. If you use the authoriative type, it will only find files that was there when you ran the command. If you ran it without any parameters, it will scan the directories each time and find classes that matches PSR-4 autoloading standard.
