fatal error Varien_Autoload not found

Goodday everyone,

I installed magento with the sample data I refreshed the page and everything seemed to work. My complete shop was filled with sample data. A couple of minutes after I refreshed again and since then I keep getting this error:

PHP Fatal error: Class 'Varien_Autoload' not开发者_Go百科 found in /var/www/vhosts/shop.cyberned.com/httpdocs/app/Mage.php on line 53

I double checked if Varien_Autoload exists and it is there in lib/Varien/Autoload.php

It looks like that file is not included for some reason but I would have no idea how to get that fixed. So my question is: how do I get this fixed?

This error occurs because of the lib folder is not in the include_path. This may happen only if the COMPILER_INCLUDE_PATH constant is defined. Most likely this constant is defined in the includes/config.php file.

I have the same problem, I did following steps and now it is working :)

1. Check Compilation mode is disabled or not in include/config.php file. if not then edit and make sure these two lines should be same as written below :-

   #define('COMPILER_INCLUDE_PATH',dirname(__FILE__).DIRECTORY_SEPARATOR.'src');
   #define('COMPILER_COLLECT_PATH',dirname(__FILE__).DIRECTORY_SEPARATOR.'stat');
   

2. Flush magento cache Storage
   sudo rm -rf var/cache/*

3. Set Correct Permission
   sudo chmod -R 755 *

4. Restart the Webserver (apache/nginx)

5. Now Verify.

Check out the permission problem, Mage.php may not have the right to load the class 'Varien_Autoload'. http://www.magentocommerce.com/wiki/groups/227/resetting_file_permissions
