Re: the white screen of death

Most of the time when I get this it is because of syntax errors.

As I mostly work on dedicated linux box, I just open a putty window
and do a tail -f of /var/logs/httpd/error_log and the cake error log
for all the $this->log(); in my code.

I have found that to be the best way to debug, as you will not always
be able 'see' something. I had this happen when I made 'site to site'
communication with xml where there was no interaction with a browser.
The trick is to add enough logging :)
