White/frozen Screen of Death
Occasionally you will run across a Joomla that fails to load the page even though you know it exists. This is caused by joomla being set to use "pretty urls" and not being configured correctly to handle them.
Symptoms:
The page is blank/white with no content loaded.
-or-
when you click on a navigation link the page seems to freeze or loads blank/white.
Reason:
The .htaccess file for the URL redirects is missing a "RewriteBase"
Solution:
Edit the .htaccess file to include(without the quotes) the following just after "RewriteEngine On" statement: "RewriteBase /"
If the joomla is in a sub folder then it should read: "RewriteBase /foldername"
