gii 404 error. Unable to use Gii - yii

Question

Following http://www.yiiframework.com/doc/blog/1.1/en/prototype.scaffold tutorial, it mentions to add some code to /blog/protected/config/main.php
return array(
......
'import'=>array(
'application.models.*',
'application.components.*',
),
'modules'=>array(
'gii'=>array(
'class'=>'system.gii.GiiModule',
'password'=>'pick up a password here',
),
),
);
These are the last few lines of my code for main.php, as you can see, I have followed instructions...
'errorHandler'=>array(
// use 'site/error' action to display errors
'errorAction'=>'site/error',
),
'log'=>array(
'class'=>'CLogRouter',
'routes'=>array(
array(
'class'=>'CFileLogRoute',
'levels'=>'error, warning',
),
// uncomment the following to show log messages on web pages
/*
array(
'class'=>'CWebLogRoute',
),
*/
),
),
),
// application-level parameters that can be accessed
// using Yii::app()->params['paramName']
'params'=>array(
// this is used in contact page
'adminEmail'=>'example#example.com',
),
'import'=>array(
'application.models.*',
'application.components.*',
),
'modules'=>array(
'gii'=>array(
'class'=>'system.gii.GiiModule',
'password'=>'pick up a password here',
),
),
);
Yet when I visit index.php?r=gii, I get the following error:
Error 404 Unable to resolve the request "gii".
FYI - I am using version 1.1.12 which is the latest stable release.
UPDATE
I deleted everything and started again, and now is working. must have done something silly en-route

Answer 1

You're already have 'modules' key of configuration array at the line 21 here http://pastebin.com/x3zWWLtm . Remove the key 'modules' which you've added manually and uncomment 'gii' in that one at line 21:
<?php
// uncomment the following to define a path alias
// Yii::setPathOfAlias('local','path/to/local-folder');
// This is the main Web application configuration. Any writable
// CWebApplication properties can be configured here.
return array(
// ...
'modules'=>array(
// uncomment the following to enable the Gii tool
/*
'gii'=>array(
'class'=>'system.gii.GiiModule',
'password'=>'Enter Your Password Here',
// If removed, Gii defaults to localhost only. Edit carefully to taste.
'ipFilters'=>array('127.0.0.1','::1'),
),
*/
),
// ...
);
I've just downloaded latest yii and created a web application:
f0t0n#lotus:~/public_html/localhost/yii$ php framework/yiic webapp ../yiiapp
Then uncommented the lines of gii module including in config as I've mentioned and it's working perfect: http://localhost/yiiapp/index.php?r=gii

Answer 2

I had the same problem and I just commented temporarily, in config/main.php, the content of the array that is the value of the rules key:
'urlManager'=>array(
'urlFormat'=>'path',
'rules'=>array(/*
'<controller:\w+>/<id:\d+>'=>'<controller>/view',
'<controller:\w+>'=>'<controller>/index',
'<controller:\w+>/<action:\w+>/<id:\d+>'=>'<controller>/<action>',
'<controller:\w+>/<action:\w+>'=>'<controller>/<action>'*/
),
'showScriptName'=>false,
),
Then I accessed gii, generated my controller and view and finally uncommented those lines.

Answer 3

Well, did you try another uri, like: localhost/site/error?
If got 404 then it's a .htaccess issue, try to save the following code in .htaccess file under your root directory:
Options +FollowSymLinks
IndexIgnore */*
RewriteEngine on
# if a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# otherwise forward it to index.php
RewriteRule ^.*$ /index.php [L]
