Migrating of site

We have migrated a site using yii framework, but having the following issue:
Fatal error : Uncaught Error: Call to undefined method Yii::createWebApplication() in /home/site/public_html/index.php:13 Stack trace: #0 {main} thrown in /home/site/public_html/index.php on line 13

Can you please help?

You probable didn’t adjust the path assigned to the $yii variable.

(moved to Yii 1.1 section)

We already changed the path to where the framework bas been installed.
the index.php page is as follows

<?php setlocale(LC_ALL, 'fr_FR'); // change the following paths if necessary $yii='/yii/framework/Yii.php'; $config=dirname(__FILE__).'/protected/config/main-humilis.php'; // remove the following lines when in production mode //defined('YII_DEBUG') or define('YII_DEBUG',false); // specify how many levels of call stack should be shown in each log message //defined('YII_TRACE_LEVEL') or define('YII_TRACE_LEVEL',3); require_once($yii); Yii::createWebApplication($config)->run();

Check the case here

It’s yii.php in original.

thanks. But it start with capital ‘Y’ in the folder.
Could it be something else?

Check declaration of createWebApplication inside YiiBase.php
public static function createWebApplication($config=null)
return self::createApplication(‘CWebApplication’,$config);

inherited in yii.php/Yii.php
class Yii extends YiiBase

or perhaps there’s some customization involved?

thanks a lot for your reply. If the site is developed using version 1.1 and we have migrated the site to a server having version 2.0. would that implicate changes in the code? Or should it work the same?

They can be installed in parallel. In Yii2 there’s a “vendor” directory for the framework.
I did some testing of missing/misnamed classes. Didn’t get the same error message.
But if createWebApplication is missing/misnamed, the error message will be like yours.

Two suggestions:
Check if YiiBase is corrupted.
Check if the Yii class inherits from YiiBase (or some other custom class to investigate further)

Ok thanks. the file is named BaseYii.php and I dont see the function createWebApplication.
Is it normal?

It may be normal if BaseYii inherits from YiiBase, similar to what I posted above.
.(assuming the class name also is BaseYii)
