CakePHP 2.1 new install Missing Controller Error - cakephp

Question

I am completely new to CakePHP and installed 2.1. I am getting this error:
Missing Controller
Error: Index.phpController could not be found.
Error: Create the class Index.phpController below in file: app\Controller\Index.phpController.php
<?php
class Index.phpController extends AppController {
}
Notice: If you want to customize this error message, create app\View\Errors\missing_controller.ctp
Stack Trace
APP\webroot\index.php line 96 → Dispatcher->dispatch(CakeRequest, CakeResponse)
ROOT\index.php line 40 → require(string)
I followed their guide at http://book.cakephp.org/2.0/en/installation/advanced-installation.html and tried everything it stated:
I enabled mod_rewrites (they were already enabled from something else)
I have all the .htaccess files in the directories
I have cake installed under my document root so I access it at localhost/cakephp/index.php
I do not know where to proceed from here. Thanks for any help you can give me.

Answer 1

Update: I just re-read your question and realized you're loading http://localhost/cakephp/index.php. Don't do that. Since you appended "index.php", it is trying to load a controller called "index.php" and the action "index" for that controller. Resulting mapped path to the "index.php controller" is app\Controller\Index.phpController.php.
Since you have the rewrites enabled, browse to http://localhost/cakephp without appending any filename.
Original answer:
Assuming you're using Apache, double-check the .htaccess in your /app/webroot directory. It should include the following:
RewriteRule ^(.*)$ index.php?/$1 [QSA,L]
Based on your error, it doesn't look like it's properly appending the path after your index.php file.

Answer 2

If you are using cakephp 2.0 or greater than rename the controller file name as the class name.
ie TaskController.php
class TasksController extends AppController {
--Your code inside class
}
I hope this will help you

the easiest solution is to stick to the "live environment" as close as possible.
this means using vhosts to use a "domain" and correctly root down to your webroot dir:

this leaves almost no room for error and also helps with other potential problems like "absolutely linked asset files" etc
