Re: White Page in manager after upgrade

Most likely your custom module does not support version 1.9. Magento. Go to the address root\app\etc\modules\ and rename the module file for example to

 

You_Custom_Module.xml.old

 

Also look at the address root\includes\config.php so that the compilation is disabled in the file. The lines should look like:

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