cPanel+WHM hosting, uploaded codeigniter files and shows blank page

"white screen" usually means errors are present, but you have display_errors turned off so you don't see them.

I would also remove these lines from your htaccess as they are unnecessary, redundant or already present in other .htaccess files that come with the framework.

Code:

RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php?/$1 [NC,L] (The first one)
RewriteCond %{REQUEST_URI} !^(/index\.php|/resources|/robots\.txt|/favicon\.ico|/templates)

You might want to try to enable followsymlinks in htaccess, as well.
