How can deploying laravel app on shared host?

I have installed a laravel app on host but faced with this error below. I've installed 2 or 3 another laravel app on shared host without any problem , I know the way but in this case i can't figure it out what is problem, I'm new in laravel.

This is error :

Symfony \ Component \ Debug \ Exception \ FatalThrowableError (E_ERROR)
Class 'Orangehill\Iseed\IseedServiceProvider' not found

Solution

I found the problem, It is better to install Laravel applications on Subdomain and Domain. After moving the application to subdomain every things worked perfectly. Also This link is a good guide for installing laravel on Subdirectory
