I am new to Laravel. I was trying to open http://localhost/test/public/ and I got Error in exception handler. I googled around and changed the permission of storage directory using chmod -R 777 app/storage but to no avail. I changed debug=>true in app.php and visited the page and got Error in exception handler: The stream or file "/var/www/html/test/app/storage/logs/laravel.log" could not be opene
