wsod

Got WSOD (White Screen of Death)? You don't know why? You are sick, because you've got lot of modules and you can't lost your time to disable them each by each to check what's wrong and at the end the reason is because of some cache? This module is for you. You will ask: But how I can enable it, if I've got still WSOD? Simply go to: /sites/all/modules/dtools/wsod/wsod_emergency.php (update your path to correct one). It's secure, if there is no wsod detected, this script will not print any technical info. You can use 'q' argument to test different paths. Read README.txt how to use it.

(Example usage: http://mysite/sites/all/modules/dtoosl/wsod_emergency.php?cmd=debug&q=us...)
Available variables:
    q - change the path (default: node)
    cmd - execute internal command
      Available commands:
        phpinfo - show PHP Info page
