Laravel Project, 500 internal server error

Question

I developed a simple application in laravel (5.6) everything works fine on my PC (windows 10/ Xamp / PHP 7.1). but when i upload the same project to a VPS running Cent OS it gives

with PHP 5.6 (which is expected)

Parse error: syntax error, unexpected '?' in /home/clarionit/public_html/ambience/c/vendor/laravel/framework/src/Illuminate/Foundation/helpers.php on line 233

with PHP 7.0 / 7.1 / 7.2

500, Internal server error.

What I have done so far?

Permissions for all files and folders are set to 777 (to see if that is a problem)
Replacing index.php code with something simpler like phpinfo() works perfectly.

Ask for any more information needed, Please tell me what can be causing the 500, internal server error.

@AbdullaNilam, I have checked the version of php running by uploading a phpinfo file, the version is php7.1 — Prakhar Thakur, Mar 19 '18 at 11:13
make it php greater than or equal to 7.1.3 and update composer and dump autoload and then check. And check the requirements of installation of laravel 5.6 [here](https://laravel.com/docs/5.6/installation) — Rahul, Mar 19 '18 at 11:14
@MarkWalet, Thanks for help, but there is nothing in the log file — Prakhar Thakur, Mar 19 '18 at 11:49

Please provide the entire StackTrace.. Simple one line won't help.. If you get only that one line in browser then go to laravel.log, copy the contents and paste it here.. — Saiyan Prince, Mar 19 '18 at 11:54
@MeysamMahmoodi, laravel log is empty. nothing interesting in the server log. — Prakhar Thakur, Mar 19 '18 at 13:38

Laravel 5.6 requirement should be installed in system

PHP >= 7.1.3
OpenSSL PHP Extension
PDO PHP Extension
Mbstring PHP Extension
Tokenizer PHP Extension
XML PHP Extension
Ctype PHP Extension
JSON PHP Extension

Once run these commands, I hope your problem will resolve.

rm -rf vendor
rm -rf storage/framework/cache/*
rm -rf storage/framework/session/*
rm -rf storage/framework/views/*
rm composer.lock
composer clear-cache
composer install

Thanks. Saved my client project in a panic ;) – Matt Wohler Jul 25 '18 at 21:15 — Matt Wohler, Jul 25 '18 at 21:15
