Blank page or white screen is shown in Magento Frontend, Backend or Magento Connect Manager.



If you see a blank page / white screen opening your Store in browser, it indicates that there is a PHP fatal error somewhere in the code of your Magento store.

This usually happens when you modified files, theme templates or modules / extensions, or installed a theme or extension which cause fatal PHP errors.



Before starting investigation please try to Disable Magento Compiler and Clear cached Magento data , in the most cases it should solve the issue.

To see the actual error message you need to login via FTP to your Store and use the following instructions:

  • Download the index.php file to your computer
    Note: for troubleshooting Magento Connect Manager changes should be done to downloader/index.php file
  • Edit the downloaded index.php file and uncomment (by removing leading hash character) the following code:
    ini_set('display_errors', 1);
    or insert this line somewhere at the top of the file.
    Note: for troubleshooting Magento Connect Manager changes should be done to downloader/index.php file
  • Try to increase PHP memory limit up to 256Mb or more by adding the following line into index.php right after ini_set('display_errors',1):
    ini_set('display_errors', 1);
    ini_set('memory_limit', '256M');
  • Upload the modified index.php file back (you can also rename original index.php to index.php.orig to be able to revert the changes)
  • Refresh Magento Store page in your browser, you should see the PHP error message now
  • Look for the solution by narrowing down search results with your error message

Please do not forget to change 'display_errors' setting back when the issue is solved.


If the error report gives no clue, to solve the issue please use the following steps:

  • Rollback all recent changes you applied to your store
  • Clear cached Magento data
  • Disable Magento Compiler
  • One by one, disable recently installed modules by changing <active>true</active> to <active>false</active> in app/etc/modules/<MODULE_NAME>.xml, where <MODULE_NAME> should be replaced with actual module name you installed recently. Flush Magento cache after each operation.
  • If you recently installed some theme, try to switch interface to a previously used one. If you can not reach admin interface, you can rename / move out theme directory under app/design/frontend/<theme_package>/<theme_name>, where <theme_package>/<theme_name> is path to your theme. Flush Magento cache after each operation. Magento will switch to default theme if it can not find a custom one.
