[support] blank screen - update

[Jamie Holly]

Notices are very, very minor problems. The "Warning: Cannot modify 
header information " is showing because you have the notices appearing 
on the browser before Drupal can send the HTTP header.

On these problems I usually start by switching Drupal back to using the 
Garland theme (install Drush and use vset theme_default garland). If the 
problem continues after that then start disabling modules, starting with 
custom ones.
