Problem with including Full Path CodeIgniter.php

[eluser]life_time_learner[/eluser]
Just stating my progress now. I have looked into the deep root of Router.php located in config folder, and found that

is_dir(APPPATH.'controllers/'.$segments[0]

part failed and show_404() function is triggered. I have specified the $route['default_controller'] = "Share";

For some reason , the server doesn't like the captical, therefore I change it to small share in the routes.php under config, and same to the file name in the controllers folder. Now instead of getting page not found error, I am getting


An Error Was Encountered

Unable to load the requested file: Media_Share/index.php


Just to clarify things, I have no problem running CI in localhost environment. And I have noticed that there are some server problems in Godaddy and they do not provide scripting help including .htaccess modification. Before I did encountered the same problem which I have ignored since I was playing with other frameworks and got no time. Now I decided to go through all the pain to find out the true reason for what is the cause of Godaddy to refuse CI.

Thank you for all of your kindly response.
