debugging / log files

Hi,
I'm trying to setup a test application on Centos 5.2 (PHP 5.04/MySQL 5.036).
The initial setup and makesite 'test' seem to have worked ok, the .ini file looks good.
However, I cannot go beyond a blank screen and so I tried to find the log files or enable debugging. In /var/www/httpd/error_log I can read this each time I call the 'test' homepage from a browser:
[Tue Feb 10 21:06:29 2009] [notice] child pid 28499 exit signal Segmentation fault (11)
This is not much of information, so can I enable xataface in debug mode and where can I find the log files?
Thanks for any help
