[support] Disappearing user login

[Tanay Sai]

Such a blank page is usually termed WSOD and d.o has a pretty exhaustive
checklist for debugging it.

https://drupal.org/node/158043

>From the checklist:
1) Enable Error Reporting by adding a snippet of code to your index.php
2) Check  Apache (and PHP) Logs
3) Do not include the closing ?> on a PHP file.
4) Check for PHP4 Syntax Errors and Incompatibility
5) ..
6)..

The list is long. More @ https://drupal.org/node/158043

Cheers
Tanay
