host laravel5.4 project on multidomain server

I am trying to host my laravel5.4 project no mutli domaion server.

• my project directory inside public_html
• i have moved contents of public directory to my project root directory(parallel to app directory)
• change path in index.php require __DIR__.'/../laravelproject/bootstrap/autoload.php';
• updated php version to 7.0

But still getting error like
