Codeigniter white page

Question

Strange issue: Last night I changed the Arecord and CNAME for a CI site of mine. Now that the changes have propagated and the site runs off a new server, domain.com just gives a blank page. There is nothing in the CI logs (level set to 3). Even a die('test') in the CI root index.php does not appear.

But, domain.com/index.php shows the homepage just fine and all other pages run ok too. On those pages, index.php is not req'd in the url

My htaccess (doubt this is the problem)

RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond $1 !\.(gif|jpe?g|png)$ [NC]
RewriteRule ^(.*)$ /index.php?$1 [L]

Could it be some kind of DNS issue? When I do a ping of domain.com I get 100% packet loss.

--- domain.com ping statistics ---
10 packets transmitted, 0 packets received, 100% packet loss

Answer 1

Fixed - the problem was caused by a blank index.html file in the root. Hopefully this will help someone one day.
