Drupal Blank Page
When setting up a drupal site and you encounter the infamous blank page problem, i.e all you get is a blank page...
It is really helpful to find out what errors are being generated on your server.
On a OS X 10.4.8 Mac, I opened a terminal window and input the following, one command on each line.
cd /
cd var/log/httpd
tail error_log
In my case, I was getting a fatal php error due to coming up against a memory limit in php. If that happens to you, go to your settings.php file and add the following in the section with all the other php directives.
ini_set('memory_limit', '24M');
But check your error log to make sure you are fixing the correct problem!

I just tried setting the memory_limit like you're suggested and it works like a charm. I've been trying to figure this for hours as I don't have access to SSH nor the error logs, until I read this post.

This fixed my blank page problem on my local install of Drupal. I couldn't check on my error log file with your commands above since I'm on 10.5.8 (different place for it, I suppose but I'm also on MAMP) but the memory limit turned out to be the problem in my case as well. Thanks!
This solved my problem. It should be more clearly documented on drupal.org.
THANKS!!!!
I was wondering what was happening, and am so glad you chose to write this.
Thank you very much for sharing it!
