How to deploy Laravel 5.1 application to CentOS 6.4 VPS (or any!) server (PHP 5.5.32)

I have a Laravel 5.1 application that I'm trying to deploy on my CentOS 6.4 VPS server. The problem is that I am getting Error 500 when trying to load the page. When I check the error log it shows me this:

PHP Fatal error: Uncaught exception 'UnexpectedValueException' with message 'The stream or file "/home/pams/pams_todo_list/storage/logs/laravel.log" could not be opened: failed to open stream: Permission denied' in /home/pams/pams_todo_list/vendor/monolog/monolog/src/Monolog/Handler/StreamHandler.php:87

I have changed the permissions in pams_todo_list/storage and pams_todo_list/vendors to 777 instead of 755 as a test, but no love.
