CodeIgniter in Ubuntu 16.04 - codeigniter

Question

I'm trying to move my CI project from my localhost in windows to Ubuntu. I'm working with:
In my cognfig.php
$config['base_url'] = '';
$config['index_page'] = 'index.php';
My Virtual Host:
<VirtualHost *:80>
# Admin email, Server Name (domain name) and any aliases
ServerAdmin mymail#mymail.com
ServerName mywebiml.com
ServerAlias www.mywebiml.com
# Index file and Document Root (where the public files are located)
DirectoryIndex index.php
DocumentRoot /var/www/html/CLASE
</VirtualHost>
The root folder of the CI application is "CLASE".
Also, I added entries in /etc/hosts
MyIp mywebiml.com
MyIp www.mywebiml.com
The problem being, I keep getting the custom 404 error from CI when I try access my page.

Answer 1

First you MUST give $config['base_url'] a value. Use the following
$config['base_url'] = 'http://mywebiml.com/';
Second, make sure you are using the file and class naming scheme CI requires. Class files must be named in a Ucfirst-like manner, while any other file name (configurations, views, generic scripts, etc.) should be in all lowercase.
Bad:
some_class.php
Good:
Some_class.php
Class names should always start with an uppercase letter. Multiple words should be separated with an underscore, and not CamelCased.
Bad:
class someClass {
Good:
class Some_class {
File names and class names must be exactly the same - case-sensitive.
The above rules won't matter on a Windows based development environment but will on a linux system like Ubuntu.
If you are using .htaccess to rewrite URLs so the index.php is removed use the following.
$config['index_page'] = '';
