Laravel 5 Server Error 500 Hosting in cpanel repost

I have posted a question yesterday here in relation with hosting a laravel project in Cpanel.

I have tried all solutions that have been proposed in several topics in relation with this problem by still having the same error.

I am sorry for republishing this just trying to get another advices & propositions maybe I have published my question in an inappropriate hour.

I can publish the content of any file you want if you think that the problem may come somewhere else.
